Adding a display to your Arduino can serve many purposes. Since a common use for microcontrollers is reading data from sensors, a display allows you to see this data in real-time without needing to use the serial monitor within the Arduino IDE. It also allows you to give your projects a personal touch with text, images, or even interactivity through a touch screen.

Transparent Organic Light Emitting Diode (TOLED) is a type of LED that, as you can guess, has a transparent screen. It builds on the now common OLED screens found in smartphones and TVs, but with a transparent display, offers up some new possibilities for Arduino screens.

Take for example this brilliant project that makes use of TOLED displays. By stacking 10 transparent OLED screens in parallel, creator Sean Hodgins has converted a handful of 2D screens into a solid-state volumetric display. This kind of display creates an image that has 3-dimensional depth, taking us one step closer to the neon, holographic screens we imagine in the future.

Crystalfontz has a tiny monochrome (light blue) 1.51" TOLED that has 128x56 pixels. As the technology is more recent than the following displays in this list, the cost is higher too. One of these screens can be purchased for around $26, but for certain applications, it might just be worth it.

The liquid crystal display (LCD) is the most common display to find in DIY projects and home appliances alike. This is no surprise as they are simple to operate, low-powered, and incredibly cheap.

This type of display can vary in design. Some are larger, with more character spaces and rows; some come with a backlight. Most attach directly to the board through 8 or 12 connections to the Arduino pins, making them incompatible with boards with fewer pins available. In this instance, buy a screen with an I2C adapter, allowing control using only four pins.

Available for only a few dollars (or as little as a couple of dollars on AliExpress with included I2C adapter), these simple displays can be used to give real-time feedback to any project.

The screens are capable of a large variety of preset characters which cover most use cases in a variety of languages. You can control your LCD using the Liquid Crystal Library provided by Arduino. The display() and noDisplay() methods write to the LCD, as shown in the official tutorial on the Arduino website.

Are you looking for something simple to display numbers and a few basic characters? Maybe you are looking for something with that old-school arcade feel? A seven-segment display might suit your needs.

These simple boards are made up of 7 LEDs (8 if you include the dot), and work much like normal LEDs with a common Anode or Cathode connection. This allows them to take one connection to V+ (or GND for common cathode) and be controlled from the pins of your Arduino. By combining these pins in code, you can create numbers and several letters, along with more abstract designs—anything you can dream up using the segments available!

Next on our list is the 5110 display, also affectionately known as the Nokia display due to its wide use in the beloved and nigh indestructible Nokia 3310.

These tiny LCD screens are monochrome and have a screen size of 84 x 48 pixels, but don"t let that fool you. Coming in at around $2 on AliExpress, these displays are incredibly cheap and usually come with a backlight as standard.

Depending on which library you use, the screen can display multiple lines of text in various fonts. It"s also capable of displaying images, and there is free software designed to help get your creations on screen. While the refresh rate is too slow for detailed animations, these screens are hardy enough to be included in long-term, always-on projects.

For a step up in resolution and functionality, an OLED display might be what you are looking for. At first glance, these screens look similar to the 5110 screens, but they are a significant upgrade. The standard 0.96" screens are 128 x 64 monochrome, and come with a backlight as standard.

They connect to your Arduino using I2C, meaning that alongside the V+ and GND pins, only two further pins are required to communicate with the screen. With various sizes and full color options available, these displays are incredibly versatile.

For a project to get you started with OLED displays, our Electronic D20 build will teach you everything you need to know -- and you"ll end up with the ultimate geeky digital dice for your gaming sessions!

These displays can be used in the same way as the others we have mentioned so far, but their refresh rate allows for much more ambitious projects. The basic monochrome screen is available on Amazon.

Thin-film-transistor liquid-crystal displays (TFT LCDs) are in many ways another step up in quality when it comes to options for adding a screen to your Arduino. Available with or without touchscreen functionality, they also add the ability to load bitmap files from an on-board microSD card slot.

Arduino have an official guide for setting up their non-touchscreen TFT LCD screen. For a video tutorial teaching you the basics of setting up the touchscreen version, YouTuber educ8s.tv has you covered:

With the touchscreen editions of these screens costing less than $10 on AliExpress, these displays are another great choice for when you need a nice-looking display for your project.

Looking for something a little different? An E-paper (or E-ink depending on who you ask) display might be right for you. These screens differ from the others giving a much more natural reading experience, it is no surprise that this technology is the cornerstone of almost every e-reader available.

The reason these displays look so good is down to the way they function. Each "pixel" contains charged particles between two electrodes. By switching the charge of each electrode, you can influence the negatively charged black particles to swap places with the positively charged white particles.

This is what gives e-paper such a natural feel. As a bonus, once the ink is moved to its location, it uses no power to keep it there. This makes these displays naturally low-power to operate.

This article has covered most options available for Arduino displays, though there are definitely more weird and wonderful ways to add feedback to your DIY devices.

Now that you have an idea of what is out there, why not incorporate a screen into your DIY smart home setup? If retro gaming is more your thing, why not create some retro games on Arduino?

Displays are one of the best ways to provide feedback to users of a particular device or project and often the bigger the display, the better. For today’s tutorial, we will look on how to use the relatively big, low cost, ILI9481 based, 3.5″ Color TFT display with Arduino.

This 3.5″ color TFT display as mentioned above, is based on the ILI9481 TFT display driver. The module offers a resolution of 480×320 pixels and comes with an SD card slot through which an SD card loaded with graphics and UI can be attached to the display. The module is also pre-soldered with pins for easy mount (like a shield) on either of the Arduino Mega and Uno, which is nice since there are not many big TFT displays that work with the Arduino Uno.

The module is compatible with either of the Arduino Uno or the Arduino Mega, so feel free to choose between them or test with both. As usual, these components can be bought via the links attached to them.

One of the good things about this module is the ease with which it can be connected to either of the Arduino Mega or Uno. For this tutorial, we will use the Arduino Uno, since the module comes as a shield with pins soldered to match the Uno’s pinout. All we need to do is snap it onto the top of the Arduino Uno as shown in the image below, thus no wiring required.

This ease of using the module mentioned above is, however, one of the few downsides of the display. If we do not use the attached SD card slot, we will be left with 6 digital and one analog pin as the module use the majority of the Arduino pins. When we use the SD card part of the display, we will be left with just 2 digital and one analog pin which at times limits the kind of project in which we can use this display. This is one of the reasons while the compatibility of this display with the Arduino Mega is such a good news, as the “Mega” offers more digital and analog pins to work with, so when you need extra pins, and size is not an issue, use the Mega.

To easily write code to use this display, we will use the GFX and TFT LCD libraries from “Adafruit” which can be downloaded here. With the library installed we can easily navigate through the examples that come with it and upload them to our setup to see the display in action. By studying these examples, one could easily learn how to use this display. However, I have compiled some of the most important functions for the display of text and graphics into an Arduino sketch for the sake of this tutorial. The complete sketch is attached in a zip file under the download section of this tutorial.

As usual, we will do a quick run through of the code and we start by including the libraries which we will use for the project, in this case, the Adafruit GFX and TFT LCD libraries.

With this done, the Void Setup() function is next. We start the function by issuing atft.reset() command to reset the LCD to default configurations. Next, we specify the type of the LCD we are using via the LCD.begin function and set the rotation of the TFT as desired. We proceed to fill the screen with different colors and display different kind of text using diverse color (via the tft.SetTextColor() function) and font size (via the tft.setTextSize() function).

Next is the void loop() function. Here we basically create a UI to display the youtube subscribe button, using some of the same functions we used under the void setup() function.

The Adafruit library helps reduce the amount of work one needs to do while developing the code for this display, leaving the quality of the user interface to the limitations of the creativity and imagination of the person writing the code.

In this Arduino touch screen tutorial we will learn how to use TFT LCD Touch Screen with Arduino. You can watch the following video or read the written tutorial below.

As an example I am using a 3.2” TFT Touch Screen in a combination with a TFT LCD Arduino Mega Shield. We need a shield because the TFT Touch screen works at 3.3V and the Arduino Mega outputs are 5 V. For the first example I have the HC-SR04 ultrasonic sensor, then for the second example an RGB LED with three resistors and a push button for the game example. Also I had to make a custom made pin header like this, by soldering pin headers and bend on of them so I could insert them in between the Arduino Board and the TFT Shield.

Here’s the circuit schematic. We will use the GND pin, the digital pins from 8 to 13, as well as the pin number 14. As the 5V pins are already used by the TFT Screen I will use the pin number 13 as VCC, by setting it right away high in the setup section of code.

I will use the UTFT and URTouch libraries made by Henning Karlsen. Here I would like to say thanks to him for the incredible work he has done. The libraries enable really easy use of the TFT Screens, and they work with many different TFT screens sizes, shields and controllers. You can download these libraries from his website, RinkyDinkElectronics.com and also find a lot of demo examples and detailed documentation of how to use them.

After we include the libraries we need to create UTFT and URTouch objects. The parameters of these objects depends on the model of the TFT Screen and Shield and these details can be also found in the documentation of the libraries.

So now I will explain how we can make the home screen of the program. With the setBackColor() function we need to set the background color of the text, black one in our case. Then we need to set the color to white, set the big font and using the print() function, we will print the string “Arduino TFT Tutorial” at the center of the screen and 10 pixels down the Y – Axis of the screen. Next we will set the color to red and draw the red line below the text. After that we need to set the color back to white, and print the two other strings, “by HowToMechatronics.com” using the small font and “Select Example” using the big font.

Now we need to make the buttons functional so that when we press them they would send us to the appropriate example. In the setup section we set the character ‘0’ to the currentPage variable, which will indicate that we are at the home screen. So if that’s true, and if we press on the screen this if statement would become true and using these lines here we will get the X and Y coordinates where the screen has been pressed. If that’s the area that covers the first button we will call the drawDistanceSensor() custom function which will activate the distance sensor example. Also we will set the character ‘1’ to the variable currentPage which will indicate that we are at the first example. The drawFrame() custom function is used for highlighting the button when it’s pressed. The same procedure goes for the two other buttons.

Ok next is the RGB LED Control example. If we press the second button, the drawLedControl() custom function will be called only once for drawing the graphic of that example and the setLedColor() custom function will be repeatedly called. In this function we use the touch screen to set the values of the 3 sliders from 0 to 255. With the if statements we confine the area of each slider and get the X value of the slider. So the values of the X coordinate of each slider are from 38 to 310 pixels and we need to map these values into values from 0 to 255 which will be used as a PWM signal for lighting up the LED. If you need more details how the RGB LED works you can check my particular tutorialfor that. The rest of the code in this custom function is for drawing the sliders. Back in the loop section we only have the back button which also turns off the LED when pressed.

In order the code to work and compile you will have to include an addition “.c” file in the same directory with the Arduino sketch. This file is for the third game example and it’s a bitmap of the bird. For more details how this part of the code work you can check my particular tutorial. Here you can download that file:

In this article, you will learn how to use TFT LCDs by Arduino boards. From basic commands to professional designs and technics are all explained here.

In electronic’s projects, creating an interface between user and system is very important. This interface could be created by displaying useful data, a menu, and ease of access. A beautiful design is also very important.

There are several components to achieve this. LEDs, 7-segments, Character and Graphic displays, and full-color TFT LCDs. The right component for your projects depends on the amount of data to be displayed, type of user interaction, and processor capacity.

TFT LCD is a variant of a liquid-crystal display (LCD) that uses thin-film-transistor (TFT) technology to improve image qualities such as addressability and contrast. A TFT LCD is an active matrix LCD, in contrast to passive matrix LCDs or simple, direct-driven LCDs with a few segments.

In Arduino-based projects, the processor frequency is low. So it is not possible to display complex, high definition images and high-speed motions. Therefore, full-color TFT LCDs can only be used to display simple data and commands.

In this article, we have used libraries and advanced technics to display data, charts, menu, etc. with a professional design. This can move your project presentation to a higher level.

Size of displays affects your project parameters. Bigger Display is not always better. if you want to display high-resolution images and signs, you should choose a big size display with higher resolution. But it decreases the speed of your processing, needs more space and also needs more current to run.

After choosing the right display, It’s time to choose the right controller. If you want to display characters, tests, numbers and static images and the speed of display is not important, the Atmega328 Arduino boards (such as Arduino UNO) are a proper choice. If the size of your code is big, The UNO board may not be enough. You can use Arduino Mega2560 instead. And if you want to show high resolution images and motions with high speed, you should use the ARM core Arduino boards such as Arduino DUE.

In electronics/computer hardware a display driver is usually a semiconductor integrated circuit (but may alternatively comprise a state machine made of discrete logic and other components) which provides an interface function between a microprocessor, microcontroller, ASIC or general-purpose peripheral interface and a particular type of display device, e.g. LCD, LED, OLED, ePaper, CRT, Vacuum fluorescent or Nixie.

The display driver will typically accept commands and data using an industry-standard general-purpose serial or parallel interface, such as TTL, CMOS, RS232, SPI, I2C, etc. and generate signals with suitable voltage, current, timing and demultiplexing to make the display show the desired text or image.

The LCDs manufacturers use different drivers in their products. Some of them are more popular and some of them are very unknown. To run your display easily, you should use Arduino LCDs libraries and add them to your code. Otherwise running the display may be very difficult. There are many free libraries you can find on the internet but the important point about the libraries is their compatibility with the LCD’s driver. The driver of your LCD must be known by your library. In this article, we use the Adafruit GFX library and MCUFRIEND KBV library and example codes. You can download them from the following links.

You must add the library and then upload the code. If it is the first time you run an Arduino board, don’t worry. Just follow these steps:Go to www.arduino.cc/en/Main/Software and download the software of your OS. Install the IDE software as instructed.

By these two functions, You can find out the resolution of the display. Just add them to the code and put the outputs in a uint16_t variable. Then read it from the Serial port by Serial.println(); . First add Serial.begin(9600); in setup().

First you should convert your image to hex code. Download the software from the following link. if you don’t want to change the settings of the software, you must invert the color of the image and make the image horizontally mirrored and rotate it 90 degrees counterclockwise. Now add it to the software and convert it. Open the exported file and copy the hex code to Arduino IDE. x and y are locations of the image. sx and sy are sizes of image. you can change the color of the image in the last input.

Upload your image and download the converted file that the UTFT libraries can process. Now copy the hex code to Arduino IDE. x and y are locations of the image. sx and sy are size of the image.

In this template, We just used a string and 8 filled circles that change their colors in order. To draw circles around a static point ,You can use sin(); and cos(); functions. you should define the PI number . To change colors, you can use color565(); function and replace your RGB code.

In this template, We converted a .jpg image to .c file and added to the code, wrote a string and used the fade code to display. Then we used scroll code to move the screen left. Download the .h file and add it to the folder of the Arduino sketch.

In this template, We used sin(); and cos(); functions to draw Arcs with our desired thickness and displayed number by text printing function. Then we converted an image to hex code and added them to the code and displayed the image by bitmap function. Then we used draw lines function to change the style of the image. Download the .h file and add it to the folder of the Arduino sketch.

In this template, We created a function which accepts numbers as input and displays them as a pie chart. We just use draw arc and filled circle functions.

In this template, We added a converted image to code and then used two black and white arcs to create the pointer of volumes. Download the .h file and add it to the folder of the Arduino sketch.

In this template, We added a converted image and use the arc and print function to create this gauge. Download the .h file and add it to folder of the Arduino sketch.

while (a < b) { Serial.println(a); j = 80 * (sin(PI * a / 2000)); i = 80 * (cos(PI * a / 2000)); j2 = 50 * (sin(PI * a / 2000)); i2 = 50 * (cos(PI * a / 2000)); tft.drawLine(i2 + 235, j2 + 169, i + 235, j + 169, tft.color565(0, 255, 255)); tft.fillRect(200, 153, 75, 33, 0x0000); tft.setTextSize(3); tft.setTextColor(0xffff); if ((a/20)>99)

while (b < a) { j = 80 * (sin(PI * a / 2000)); i = 80 * (cos(PI * a / 2000)); j2 = 50 * (sin(PI * a / 2000)); i2 = 50 * (cos(PI * a / 2000)); tft.drawLine(i2 + 235, j2 + 169, i + 235, j + 169, tft.color565(0, 0, 0)); tft.fillRect(200, 153, 75, 33, 0x0000); tft.setTextSize(3); tft.setTextColor(0xffff); if ((a/20)>99)

In this template, We display simple images one after each other very fast by bitmap function. So you can make your animation by this trick. Download the .h file and add it to folder of the Arduino sketch.

In this template, We just display some images by RGBbitmap and bitmap functions. Just make a code for touchscreen and use this template. Download the .h file and add it to folder of the Arduino sketch.

In electronics world today, Arduino is an open-source hardware and software company, project and user community that designs and manufactures single-board microcontrollers and microcontroller kits for building digital devices. Arduino board designs use a variety of microprocessors and controllers. The boards are equipped with sets of digital and analog input/output (I/O) pins that may be interfaced to various expansion boards (‘shields’) or breadboards (for prototyping) and other circuits.

The boards feature serial communications interfaces, including Universal Serial Bus (USB) on some models, which are also used for loading programs. The microcontrollers can be programmed using the C and C++ programming languages, using a standard API which is also known as the “Arduino language”. In addition to using traditional compiler toolchains, the Arduino project provides an integrated development environment (IDE) and a command line tool developed in Go. It aims to provide a low-cost and easy way for hobbyist and professionals to create devices that interact with their environment using sensors and actuators. Common examples of such devices intended for beginner hobbyists include simple robots, thermostats and motion detectors.

In order to follow the market tread, Orient Display engineers have developed several Arduino TFT LCD displays and Arduino OLED displays which are favored by hobbyists and professionals.

Although Orient Display provides many standard small size OLED, TN and IPS Arduino TFT displays, custom made solutions are provided with larger size displays or even with capacitive touch panel.

In this article, let us see a list of Display Devices compatible with Arduino. These range from simple character displays to big graphical displays with touchscreen capabilities. Use this tutorial as a comparison of Arduino Display Devices which you can use in your DIY Project.

A Display is an output device used to present information in visual form. Using a Display device in your Arduino or any other DIY Project is definitely an advantage as you can easily view the data / information on the display instead of, say, the serial monitor.

There are several types of Display Devices available in the market that are compatible with Arduino with nice libraries. But choosing the right display for the project is an important task as you have to consider several aspects like price, size, resolution, ease-of-use, availability of libraries etc.

I collected a list of some of the commonly used Arduino compatible Display Devices. I also added links to tutorials for that particular display device using Arduino. Take a look at the list and I hope it helps in narrowing down the right display for your next Arduino Project.

Perhaps the most commonly used Display Device with Arduino is the 16×2 LCD. It is an alphanumeric character display which means that this LCD is capable of displaying only numbers and characters (and very few custom characters).

The numbers 16×2 represents the number of characters (16) per row and total number of rows (2). There is also a slightly bigger version of this display called the 20×4 LCD. As expected, it has 4 rows and 20 characters per row.

8-bit or 4-bit Parallel Communication is the only way for Arduino to communicate with a 16×2 LCD. Since this interface takes up a lot of Arduino’s pins, PCF8574 based I2C add-on boards are developed for 16×2 LCD.

Using I2C based LCD reduces the required pins to just two (SCL an SDA of I2C). I made dedicated tutorial on “Interfacing 16×2 LCD with Arduino” and also on “How to Connect I2C LCD with Arduino”.

The next useful display device for Arduino is the monochrome OLED Display. OLED Displays have self-illuminating pixels i.e., each pixel is capable of producing its own light. So, there is no need for any backlight.

Coming to the communication, OLED Displays are available in two interface options: SPI and I2C. Both look very similar except that pins are different in both these devices.

The advantage of OLED over traditional Character LCDs is that it is a Graphical Display, which means, it is very easy to display bitmap images and characters with different fonts.

Originally developed for use in Nokia Mobile Phones, the Nokia 5110 LCD is slowly becoming a popular choice for Arduino Projects. It has a resolution of 84×48 pixels and it is a Graphical LCD.

For Backlight, there are several options like Red, Blue, Green and White. I made dedicated tutorial on “Interfacing Nokia 5110 LCD with Arduino”. Check it out if you are interested.

Since the Nokia 5110 is a graphical LCD, it is very easy to design a Graphical User Interface for your application, like a Menu System. Do check the “How to Design an Arduino Nokia 5110 LCD Menu System?” tutorial.

The next useful display device in the list is the 128×64 Graphical LCD. As the name suggests, it has a resolution of 128×64 pixels, which is greater than a Nokia 5110 LCD. Also, the size of the LCD is big, with a lot of real estate to work with.

It is very important to know the LCD Controller used in the LCD Device as there are many options available and you have to select the appropriate Controller in the code. Some of the common controllers are:

Technically not a display device like the previous devices in the list, the 8×8 LED Matrix is an interesting visual device for sure. An 8×8 Matrix LED is a two-dimensional array of LEDs, which can display numbers, characters, simple graphical figures etc.

Hence, dedicated Display Driver ICs like MAX7219 are used to build modules around 8×8 LED Matrix so that Arduino (or other Microcontrollers) can communicate with MAX7219 through SPI.

It is very easy to cascade multiple such modules to increase the pixel count. Visit the “Arduino 8×8 LED Matrix” tutorial to find out more about 8×8 LED Matrix.

A Seven Segment Display or 7 Segment Display is another simple display device that you can use with Arduino. If your application requires displaying only numbers like Time or Quantity, then a 7 Segment Display is the cheapest and easiest option.

As the name suggests, a 7-Segment Display consists of, well, 7 LEDs arranged in “Segments” to form an “8”. It is very easy to display digits from 0 to 9. Depending on the internal orientation of the LEDs, a 7-Segment Display can be either a Common Cathode Device or a Common Anode Device.

One common configuration of 7 Segment Display is its availability as 4 – Digit Modules. Individual Seven Segment Displays also consists of a decimal point as a part of it.

For more information on 7 Segment Displays, visit, “Arduino 7 Segment Display Interface” and for 4 – digit 7 – Segment Display, visit, “Arduino 4-Digit 7-Segment LED Display”.

The next two Arduino Display Devices are advanced modules (and even costly). If you want to create intuitive GUI (Graphical User Interface) between the system and the end user, then a colourful TFT LCD Display is your best option.

In normal TFT LCD Displays, you can only display the information. In order to interact with the system, you need additional hardware like a Rotary Encoder or Push Buttons. The TFT Touchscreen LCD Display solves this problem by integrating touchscreen on to the TFT Display.

NOTE: I did not implement any project using TFT LCD Display and TFT Touchscreen LCD Display. I will update the links for tutorial once I complete those projects.

This was a brief look at 8 of the most common Arduino Display Devices to integrate in your project. Interfacing a Display Device with Arduino will certainly give your project a new look and finish, whether it is a simple Alarm Clock, Weather Station or a complex Menu Interface.

No! For about the price of a familiar 2x16 LCD, you get a high resolution TFT display. For as low as $4 (shipping included!), it"s possible to buy a small, sharp TFT screen that can be interfaced with an Arduino. Moreover, it can display not just text, but elaborate graphics. These have been manufactured in the tens of millions for cell phones and other gadgets and devices, and that is the reason they are so cheap now. This makes it feasible to reuse them to give our electronic projects colorful graphic displays.

There are quite a number of small cheap TFT displays available on eBay and elsewhere. But, how is it possible to determine which ones will work with an Arduino? And what then? Here is the procedure:ID the display. With luck, it will have identifying information printed on it. Otherwise, it may involve matching its appearance with a picture on Google images. Determine the display"s resolution and the driver chip.

Find out whether there is an Arduino driver available. Google is your friend here. Henning Karlsen"s UTFT library works with many displays. (http://www.rinkydinkelectronics.com/library.php?i...)

Download and install the driver library. On a Linux machine, as root, copy the library archive file to the /usr/share/arduino/libraries directory and untar or unzip it.

Load an example sketch into the Arduino IDE, and then upload it to the attached Arduino board with wired-up TFT display. With luck, you will see text and/or graphics.

We"ll begin with a simple one. The ILI9163 display has a resolution of 128 x 128 pixels. With 8 pins in a single row, it works fine with a standard Arduino UNO or with a Mega. The hardware hookup is simple -- only 8 connections total! The library put together by a smart fella, by the name of sumotoy, makes it possible to display text in multiple colors and to draw lines.

Note that these come in two varieties, red and black. The red ones may need a bit of tweaking to format the display correctly -- see the comments in the README.md file. The TFT_ILI9163C.h file might need to be edited.

It is 5-volt friendly, since there is a 74HC450 IC on the circuit board that functions as a level shifter. These can be obtained for just a few bucks on eBay and elsewhere, for example -- $3.56 delivered from China. It uses Henning Karlsen"s UTFT library, and it does a fine job with text and graphics. Note that due to the memory requirement of UTFT, this display will work with a standard UNO only with extensive tweaking -- it would be necessary to delete pretty much all the graphics in the sketch, and just stay with text.

on the far side of the display. It has 220x176 resolution (hires!) and will accept either 3.3 or 5 volts. It will work hooked up to an Uno, and with a few pin changes, also with a Mega. The 11-pin row is for activating the display itself, and the 5-pin row for the SD socket on its back.

This one is a 2.2" (diagonal) display with 176x220 resolution and parallel interface. It has a standard ("Intel 8080") parallel interface, and works in both 8-bit and 16-bit modes. It uses the S6D0164 driver in Henning Karlsen"s UTFT library, and because of the memory requirements of same, works only with an Arduino Mega or Due. It has an SD card slot on its back

This one is a bit of an oddball. It"s a clone of the more common HY-TFT240, and it has two rows of pins, set at right angles to one another. To enable the display in 8-bit mode, only the row of pins along the narrow edge is used. The other row is for the SD card socket on the back, and for 16-bit mode. To interface with an Arduino ( Mega or Due), it uses Henning Karlsen"s UTFT library, and the driver is ILI9325C. Its resolution is 320x240 (hires!) and it incorporates both a touch screen and an SD card slot.

Having determined that a particular TFT display will work with the Arduino, it"s time to think about a more permanent solution -- constructing hard-wired and soldered plug-in boards. To make things easier, start with a blank protoshield as a base, and add sockets for the TFT displays to plug into. Each socket row will have a corresponding row next to it, with each individual hole "twinned" to the adjacent hole in the adjoining row by solder bridges, making them accessible to jumpers to connect to appropriate Arduino pins. An alternative is hard-wiring the socket pins to the Arduino pins, which is neater but limits the versatility of the board.

In step 5, you mention that the TFT01 display can"t be used with the UTFT library on an Arduino Uno because of its memory requirements. It can - all you have to do is edit memorysaver.h and disable any display models you"re not using.

I think you should add a disclaimer that the code might make the Arduino Uno unprogrammable afterward (due to use up the two 0 and 1 pin) and link to how to fix it: https://stackoverflow.com/questions/5290428/how-to-reset-an-arduino-board/8453576?sfb=2#84535760

Not at all - it was your Instructable that got me going with the display to begin with! We all build off each other"s work, to the benefit of everyone.0

Tho I realize this is quickly becoming legacy hardware, these 8,16 bit parallel spi with 4 wire controller 3.2in Taft touch display 240x380. It has become very inexpensive with ally of back stock world wide so incorporating them into any project is easier then ever. Sorry to my question. I’m having difficulty finding wiring solution for this lcd. It is a sd1289 3.3 and 5v ,40 pin parallel 8,16 bit. I do not want to use a extra shield,hat or cape or adapter. But there’s a lot of conflicting info about required lvl shifters for this model any help or links to info would be great .. thank you. I hope I gave enough information to understand what I’m adoing

#1 you need a data sheet for the display and pinout and the i/o board attached to the cable.Than before you buy check for a driver for this chip Raydium/RM69071.if no driver lib are you able to write one and do you have the necessary tools to work on this scale to wire it up ..if you answer no than search for an arduino ready product.WCH0

hooking up and adding a lib is no piece of cake insure the screen you buy is arduino ready and sold by a reputable shop with step by step directions...WCH0

I"m sorry that I can"t help you with this. You"ll have to do your own research. See if you can identify the chipset and find out if there"s an Arduino driver for it.0

Thanks for the wealth of knowledge! It is amazing at what is possible with items the average person can easily acquire. I hope to put some of your tips to use this winter as I would like to build sensors and other items for home automation and monitoring. Being able to have small displays around the house in addition to gathering and controlling things remotely will help the family see room conditions without going to the computer. The idea of a touchscreen control for cheap is mind blowing.

This TFT display is big (3.5" diagonal) bright and colorful! 480x320 pixels with individual RGB pixel control, this has way more resolution than a black and white 128x64 display.

This display has a controller built into it with RAM buffering so that almost no work is done by the microcontroller. The display can be used in two modes: 8-bit or SPI. For 8-bit mode, you"ll need 8 digital data lines and 4 or 5 digital control lines to read and write to the display (12 lines total). SPI mode requires only 5 pins total (SPI data in, data out, clock, select, and d/c) but is slower than 8-bit mode.

As I can read your link, the shield is using D2-D8 and A0-A3, leaving some pins unused. So some Arduino pins are still free to use, just the shield is in the way to get connected there.

brutally solder some wires to the shield unused pins from front side and use that wires to connect where you want (sensors, breadboard, universal PCB, ...)

create intermediate shield (there are many, which allow you connect to arduinou on bottom and stack antother shield on top, draw your wires from there (and maybe even put some circuities on the middle shield, if you want

(something like this https://www.aliexpress.com/item/UNO-Prototype-DIY-shield-kit-for-Arduino-UNO-Universal-Extend-Board-UM-UNO/32555004112.html or any "arduino universal shield"

use pins D10-D13 as they are connected also to ISP header https://www.arduino.cc/en/Tutorial/ArduinoISP and could be connected from there. As they are part of SPI interface

It is possible to connect more arduinos, there are so much different ways, that it is hard to write here all - choose one, that would suit you best. (anyway you would need some access to some pins anyway )

There is little information on the Internet with a combination of this 1.77 inch TFT LCD work on Arduino Mega board. Most of the information is covering the 1.8 inch TFT LCD, and it is a little bit tricky to make this works since the connections on the board, and the code/driver may be different from other LCDs. We use this opportunity to explain the technology behind it besides just showing the readers its schematics. Later, we"ll show how to display both the temperature and humidity on the LCD with the DHT-11 sensor.

In a simple analogy, a computer uses a computer program, device driver, to talk to hardware like a printer and in the Arduino board, there is a microcontroller also uses some drivers to communicate with the LCD device. The communication between the microcontroller and devices can be parallel and/or serial when we look at it from the data transmission level. When we wired two LED lights with two separate I/O PINs on the board, we let the microcontroller sending the data in a parallel fashion. In the serial transmission, the data transmit one bit of data at a time, sequentially, over a communication channel called the bus. In web programming, we have the luxury of sending more complex data on a broader bandwidth, like JSON, a key-value pair data, when comparing with the low-level programming in electronics. There is a pulsing technique controlled by a clock, transmitting one bit every clock pulse. In this way, it compensates for the narrow path for data to pass through while maintaining the understanding of who is talking to whom or how to interpret the pieces of bit information that a device receives. With the clock speed, we can distinguish the data chunk out from the signal stream. It acts like traffic lights in the busiest city where all devices in the SPI bus shared the same clock as it maintains the data flow synchronized and controlled. As a result, paired its data line with a clock signal, the data is transferred synchronously. Many protocols are using this type of methods to communicate, such as SPI, and I2C. In our case, the LCD uses the Serial Peripheral Interface (SPI) protocol to communicate with the microcontroller on the Arduino board. Just like on the Internet, HTTP is a protocol for data communication between a web server and a client computer.

The sequence of the events in serial data transmission is initialized when the SS pin set low as in active mode for the slave device. Otherwise, it simply ignores the data sent from the master or the microcontroller on the Arduino board in this scenario since all devices on the SPI bus share the MISO, MOSI, and SCLK lines and the message arrives at the slave devices at the same time. Only the devices that the master wants to communicate have its SS pin set low. During the data transmission, the master begins to toggle the clock line up and down at speed supported by the slave device. For each clock cycle, it sends one bit on the MOSI line, and receive one bit on the MISO line. Until stopping the toggling of the clock line, the transmission is complete, and now the SS pin is returned with a high state. A reset is triggered, and the next sequence of data transmission can be started again. It looks like a controlled escalator moving people up and down in light speed!

Adafruit_ST7735 tft = Adafruit_ST7735(TFT_CS, TFT_DC, TFT_MOSI, TFT_SCLK, TFT_RST);Two constructors in this class mean that there are two ways to create the tft object. For 1.8 inch LCD, you should use the first constructor shown above. In our case, the 1.77 inch LCD requires us to use the second constructor.

I hope this article helps you set up the 1.77 inch TFT LCD successfully. Sometimes it is difficult to know which library to use when your manufacturer does not provide you with anything else except this label on the package. Remember to make sure that the background and text colors must be different to display characters or else you cannot see anything.

An LCD display (Liquid Crystal Display) is a flat panel display that uses the light modulating properties of liquid crystals. Since liquid crystals do not emit light, this type of display needs a backlight, or external light to produce an image. That’s why the power consumption of these displays is relatively high for battery powered Arduino projects.

On the other hand, the price of the LCDs is very low. The Nokia 5110, the 1.8″ Color TFT display and the 3.5″ Color TFT display, are all displays that use the LCD technology.

An OLED display is a screen that uses organic light emitting diodes. It requires no backlight, so the power consumption of these display is low and depends on how many pixels are lit. Also, since the screen does not need a backlight, it can display deep black color. Another advantage of this kind of display is that they are usually thinner and lighter the LCD displays. In low light, OLED displays can achieve better contrast in comparison to LCDs.

On the other hand, OLED displays are more expensive than LCD displays. Because of this, the available OLED displays for Arduino are tiny in size, and until recently they were only monochrome. A few months ago a small Color OLED appeared at a relatively low cost.

E-Paper of Electronic paper are displays that unlike traditional LCD or OLED displays does not emit light but reflect light. It is like the ink on the paper. This characteristic makes e-paper displays very comfortable to read, and they have an excellent readability under direct sunlight. Another great thing about e-paper displays is that they can hold static text and image for months without electricity! Yes, that’s correct, the display can show text and image even if it is off! That makes e-paper displays ideal for low powered projects!

Unfortunately there some disadvantages as well. The price of e-paper display is still very high. For example, this 4.3″ E-Paper display for Arduino costs over $60. Another significant disadvantage is that e-paper displays take a lot of time to update, as much as 2-3 seconds. So, they are only helpful for static text and images and not animations.

The Nokia 5110 is a basic graphic LCD screen which was originally intended for as a cell phone screen. It uses the PCD8544 controller which is a low power CMOS LCD controller/driver. Because of this, this display has an impressive power consumption. It uses only 0.4mA when it is on, but the backlight is disabled. It uses less than 0.06mA when in sleep mode! That’s one of the reasons that make this display my favorite. The PCD8544 interfaces to microcontrollers through a serial bus interface. That makes the display very easy to use with Arduino.

This impressive library is developed by Henning Karlsen who has put an enormous amount of effort to help the Arduino community move forward with his libraries. I have prepared a detailed tutorial on how to use the Nokia 5110 LCD display with Arduino. You watch it in this video:

This is a very new display, and it quickly became one of my favorites, because it uses the OLED technology, it can display 65.000 colors, it is very small, very bright and it has low power consumption.

Furthermore, it is also straightforward to use with Arduino since there is a library for it. It is the Adafruit SSD1331 library, and you find it here.

Also, despite the fact that this display is tiny, it is one of my favorites because it is ideal for handheld projects. Its power consumption is around 10-20 mA, and it depends on how many pixels are lit.

First of all the ST7735 Color TFT display is a very inexpensive display. It costs around $5, and it has a great library support. I have used it many of my projects, and I think it is great!

Furthermore, the display offers a resolution of 160×128 pixels, and it can display 65.000 colors. It uses the SPI interface to communicate with the Arduino boards. In addition to that, it works well with all the available Arduino boards, like the Arduino Uno, the Arduino Mega, and the Arduino Due. It also works fine with ESP8266 based boards, like the Wemos D1 and the Wemos D1 mini board.

In conclusion, this is one of the best Arduino displays if you need color and low cost. I have prepared a detailed tutorial about the 1.8″ ST7735 Color TFT display, you can watch it here:

This is another very nice display to use with Arduino. It is an OLED display and that means that it has a low power consumption. The power consumption of this display is around 10-20 mA and it depends on how many pixels are lit.

The display has a resolution of 128×64 pixels and it is tiny in size. Furthermore, it is very bright, and it has a great library support. Adafruit has developed a very nice library about this display, and you can find this library here.

In addition to that, the display uses the I2C interface, so the connection with Arduino is incredibly easy. You only need to connect two wires except for Vcc and GND. If you are new to Arduino and you want an inexpensive and easy to use display to use with your project, start with display. It is the easiest way to add a display to your Arduino project.

This 3.5″ Color TFT display is the biggest display that you can use in your project if you are using an Arduino Uno or a Mega. Unfortunately, it does not support the fast Arduino Due, nor the Wemos D1 ESP8266 board.

One of the biggest advantages of this display except it big size is its impressive resolution. The resolution of the display is 480×320 pixels! In addition to that, the display offers an SD card reader at the back so that you can store data.

Also, the display comes as a shield. So, you only have to connect the display with your Arduino board, and you are ready to use it. Of course, you need to install the appropriate driver for the display. Luckily I have a link to this driver here. Search for the download file, and you will find the library for the display in that .zip file.

In conlcusion, this display is a very easy to use display and it is ideal for beginners. Additionally you can use this display if you want to add a big display in your project. If fast refresh rate is not a requirement of your project, this display is a great display to use!

This post is an introduction to the Nextion display with the Arduino. We’re going to show you how to configure the display for the first time, download the needed resources, and how to integrate it with the Arduino UNO board. We’ll also make a simple graphical user interface to control the Arduino pins.

Nextion is a Human Machine Interface (HMI) solution. Nextion displays are resistive touchscreens that makes it easy to build a Graphical User Interface (GUI). It is a great solution to monitor and control processes, being mainly applied to IoT applications.

The Nextion has a built-in ARM microcontroller that controls the display, for example it takes care of generating the buttons, creating text, store images or change the background. The Nextion communicates with any microcontroller using serial communication at a 9600 baud rate.

To design the GUI, you use the Nextion Editor, in which you can add buttons, gauges, progress bars, text labels, and more to the user interface in an easy way. We have the 2.8” Nextion display basic model, that is shown in the following figure.

The best model for you, will depend on your needs. If you’re just getting started with Nextion, we recommend getting the 3.2” size which is the one used in the Nextion Editor examples (the examples also work with other sizes, but you need to make some changes). Additionally, this is the most used size, which means more open-source examples and resources for this size.

Connecting the Nextion display to the Arduino is very straightforward. You just need to make four connections: GND, RX, TX, and +5V. These pins are labeled at the back of your display, as shown in the figure below.

You can power up the Nextion display directly from the Arduino 5V pin, but it is not recommended. Working with insufficient power supply may damage the display. So, you should use an external power source. You should use a 5V/1A power adaptor with a micro USB cable. Along with your Nextion display, you’ll also receive a USB to 2 pin connector, useful to connect the power adaptor to the display.

The best way to get familiar with a new software and a new device is to make a project example. Here we’re going to create a user interface in the Nextion display to control the Arduino pins, and display data.

The user interface has two pages: one controls two LEDs connected to the Arduino pins, and the other shows data gathered from the DHT11 temperature and humidity sensor;

We won’t cover step-by-step how to build the GUI in the Nextion display. But we’ll show you how to build the most important parts, so that you can learn how to actually build the user interface. After following the instructions, you should be able to complete the user interface yourself.

Additionally, we provide all the resources you need to complete this project. Here’s all the resources you need (be aware that you may need to change some settings on the user interface to match your display size):

We’ll start by adding a background image. To use an image as a background, it should have the exact same dimensions as your Nextion display. We’re using the 2.8” display, so the background image needs to be 240×320 pixels. Check your display dimensions and edit your background image accordingly. As an example, we’re using the following image:

At this moment, you can start adding components to the display area. For our project, drag three buttons, two labels and one slider, as shown in the figure below. Edit their looks as you like.

All components have an attribute called objname. This is the name of the component. Give good names to your components because you’ll need them later for the Arduino code. Also note that each component has one id number that is unique to that component in that page. The figure below shows the objname and id for the slider.

You should trigger an event for the touchable components (the buttons and the slider) so that the Arduino knows that a component was touched. You can trigger events when you press or when you release a component.

Our second page will display data from the DHT11 temperature and humidity sensor. We have several labels to hold the temperature in Celsius, the temperature in Fahrenheit, and the humidity. We also added a progress bar to display the humidity and an UPDATE button to refresh the readings. The bBack button redirects to page0.

Notice that we have labels to hold the units like “ºC”, “ºF” and “%”, and empty labels that will be filled with the readings when we have our Arduino code running.

Once the GUI is ready, you need to write the Arduino code so that the Nextion can interact with the Arduino and vice-versa. Writing code to interact with the Nextion display is not straightforward for beginners, but it also isn’t as complicated as it may seem.

A good way to learn how to write code for the Arduino to interact with the Nextion display is to go to the examples folder in the Nextion library folder and explore. You should be able to copy and paste code to make the Arduino do what you want.

The first thing you should do is to take note of your components in the GUI that will interact with the Arduino and take note of their ID, names and page. Here’s a table of all the components the code will interact to (your components may have a different ID depending on the order you’ve added them to the GUI).

Finally, you need a function for the bUpdate (the update button). When you click this button the DHT temperature and humidity sensor reads temperature and humidity and displays them on the corresponding labels, as well as the humidity on the progress bar. That is the bUpdatePopCallback() function.

In this post we’ve introduced you to the Nextion display. We’ve also created a simple application user interface in the Nextion display to control the Arduino pins. The application built is just an example for you to understand how to interface different components with the Arduino – we hope you’ve found the instructions as well as the example provided useful.

In our opinion, Nextion is a great display that makes the process of creating user interfaces simple and easy. Although the Nextion Editor has some issues and limitations it is a great choice for building interfaces for your electronics projects. We have a project on how to create a Node-RED physical interface with the Nextion display and an ESP8266 to control outputs. Feel free to take a look.
