In this guide we’re going to show you how you can use the 1.8 TFT display with the Arduino. You’ll learn how to wire the display, write text, draw shapes and display images on the screen.

The 1.8 TFT is a colorful display with 128 x 160 color pixels. The display can load images from an SD card – it has an SD card slot at the back. The following figure shows the screen front and back view.

This module uses SPI communication – see the wiring below . To control the display we’ll use the TFT library, which is already included with Arduino IDE 1.0.5 and later.

The TFT display communicates with the Arduino via SPI communication, so you need to include the SPI library on your code. We also use the TFT library to write and draw on the display.

In which “Hello, World!” is the text you want to display and the (x, y) coordinate is the location where you want to start display text on the screen.

The 1.8 TFT display can load images from the SD card. To read from the SD card you use the SD library, already included in the Arduino IDE software. Follow the next steps to display an image on the display:

Note: some people find issues with this display when trying to read from the SD card. We don’t know why that happens. In fact, we tested a couple of times and it worked well, and then, when we were about to record to show you the final result, the display didn’t recognized the SD card anymore – we’re not sure if it’s a problem with the SD card holder that doesn’t establish a proper connection with the SD card. However, we are sure these instructions work, because we’ve tested them.

In this guide we’ve shown you how to use the 1.8 TFT display with the Arduino: display text, draw shapes and display images. You can easily add a nice visual interface to your projects using this display.

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.

This project involves yet another Arduino-compatible display which can be used as an output to display any information in the form of graphics, text or animations. Since this is a 1.3" 240x240 IPS (In-Plane Switching) TFT display module, it does offer a high-resolution colour display with fine graphics, and that is one of the things which I really enjoy about this display. It is also very easy to program, as it runs on the STT789 display, which is helpful to know, as the Adafruit ST7789 library supports this display, and is what we will be using today. The code used below is a fairly complex code at first, which showcases this display"s capabilities and what it can do, in terms of functionality. For the wiring, a 6-pin wiring configuration is used with the SPI interface to the Arduino, which will be shown below. Finally, for this project, here are the components which you will need:1 1.3" 240x240 IPS TFT Display Module

This project is fairly​ straightforward to set up so make sure you start by unplugging any power source feeding into your Arduino to prevent any shorts while wiring. Firstly, take a jumper wire and connect the GND pin on the display to any of your Arduino"s GND pins and follow that up by connecting the VCC pin from the display to the 3v3 pin of your Arduino to supply a +3.3 volt power supply to the module. +5v will have a possibility to damage the display. Now, for the i2c connections, hook up the SCL (Serial Clock) pin of the display to A13 (analog pin 13) on the Arduino and the SDA (Serial Data) pin to A11 (analog pin 11). For the RES (Reset) pin, connect it up to A8 (analog pin 8) as well as the DC (Data/Command) pin to A9 (analog pin 9). The hardware part is finally done!

This code may seem slightly intimidating at first, due to its length and much newer functions, but once it is broken down, it isn"t so hard anymore. In the first three lines, we declare libraries for running this display, the graphics used, and for the interface used, which is the SPI interface. In the next three lines, the RST (Reset) and DC (Data/Command) pins are defined, which are connected to A8 (analog pin 8) and A9 (analog pin 9). In the next line, we initialize the Adafruit ST7789 library for use with this display and we follow that by defining the value of pi as a float variable in that next line. We will be using this float variable later on for graphics and calculations needed. Thevoid setupsection is now here where we first start by begining serial communication with a baud rate of 9600 bauds and printing a test message which is "Hello! ST7789 TFT Test!". In regards to the display, we address that our display module is of 240x240 resolution and we set the rotation of our display in the next line. If your display is flipped, removetft.setRotation(2)​. From there, we print the text "Initialized" as our display is now correctly set up. After that, we count up the seconds from the startup with themillis()function and store it in an unsigned 16-bit integer, namedtime, for use later. We then fill up the TFT screen with a black colour. Since we already started the stopwatch which counts up, we can always reset the stopwatch back to zero by using subtracting thetimefunction with themillis()​.To end off this section, we set a delay for 500 milliseconds before moving on. This section onwards will only be for the animations, graphics and images displayed on the screen, and we start off by filling the screen with a black background and writing some text with a white colour before a 1-second delay. Proceeding that, we execute a print test which basically is already programmed to print out a set of text in different font colours and sizes. We end this test by setting a delay for 4 seconds. From this point, the rest of the code is responsible for printing out the different graphics, which can be composed of shapes, pixels and text. All the different graphics and its individual code are mentioned at the end of the code so I recommend really going through this program to learn all the commands, which can help you build your own demo code, even with your own personal images being displayed. This project is now done!

The Arduino TFT screen is a backlit TFT LCD screen with a micro SD card slot in the back. You can draw text, images, and shapes to the screen with the TFT library.

The Arduino TFT library extends the Adafruit GFX, and Adafruit ST7735 libraries that it is based on. The GFX library is responsible for the drawing routines, while the ST7735 library is specific to the screen on the Arduino screen. The Arduino specific additions were designed to work as similarly to the Processing API as possible.

The TFT library relies on the SPI library, which must be included in any sketch that uses the scree. If you wish to use the SD card, you need to include the SD library as well.

If you are using an Esplora, the structure of the program is the exact same. As the Esplora has a socket designed for the screen, and the pins for using the screen are fixed, an Esplora only object is created when targeting sketches for that board. You can reference the screen attached to an Esplora throughEsploraTFT.

To give the illusion of motion, you need to quickly erase and draw images on the screen. When using Processing on a powerful computer, you can callbackground() every time through your draw() function to erase the window contests and dra objects in their new positions. The Arduino is not as fast, is it takes a little time to clear the screen when calling background() with the TFT library.

The TFT library includes a basic font for drawing text on screen. By default, characters are 5 pixels wide and 8 pixels tall. It is possible to change the font size to 10x16, 15x24, or 20x32. For additional information on the underlying font capabilities, see the Adafruit page on graphic primitives.

The TFT library has the ability to read .bmp files off a SD card and display them on the screen. Images can be smaller or larger than the screen resolution (160x128), but there is no method on the Arduino for image manipulation. The images should be sized before you put them on the SD card.

Connecting the pins in the proper way, you can see the lcd screen working with your Uno (or Duemilanove) just uploading the simple "TFTBitmapLogo" sketch.

The Arduino Leonardo & Arduino Yún use different pins to be compatible with the lcd screen. To set the pins MISO, MOSI and SCK, you have to use the ICSP terminals.+5V:+5V

The screen will show this message: "Arduino TFT Bitmap Example. Open serial monitor to run the sketch". Open the serial monitor to view the Arduino Logo.

To connect the lcd screen to an Arduino Due, use this pin configuration and don"t forget to set the right value for the variable "sd_cs" (#definesd_cs7) in the sketch:+5V:+3.3V

Now that you have tested the basic functionality of the screen, see the TFT library pages for information about the library"s API and additional examples. It"s also recommended to visit the Adafruit graphics library page for additional information on functions not covered.

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.

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.

TFT LCD (thin-film transistor liquid crystal display) or TFT display is a type of Liquid Crystal Display (LCD) that uses thin-film transistor technology to improve features such as contrast and addressability. TFT display technology powers each individual pixel with a single transistor, resulting in faster response times.

TFT LCD technology uses "field-effect" transistors that are built by layering thin films on a glass substrate, hence the name. This method is commonly used to construct microprocessors. The TFT display module in the LCD controls individual pixels in the display by adjusting the amount of electric field across the three liquid crystal capacitors (one for each sub-pixel of red, green, and blue) in the pixel. This has an impact on the polarisation of the crystal material. How much backlighting reaches the colour filter is determined by the amount of polarisation in the crystal. Because of its ability to manipulate each pixel quickly and directly, TFT modules are also known as active-matrix LCD technology.

TFT screen: When it comes to cameras TFT stands for "Thin-Film-Transistor" liquid-crystal display. TFT display technology enables the development of high-resolution LCD display screens with superior contrast performance. TFT displays are used by camera manufacturers because they allow LCD displays to display high-resolution, colour-accurate replicas of acquired images. This eliminates the need to upload photographs to a higher resolution display device and allows photographers to accurately evaluate their work while it is still in progress. TFT displays are used in devices other than cameras, such as home televisions, mobile phones, and computer monitors.

The Arduino"s backlit TFT LCD screen has a micro SD card port on the back. You can draw text, pictures, and shapes on the screen using the TFT library. Although it can be used with any Arduino board, the pin configuration of the TFT display Arduino screen is designed to fit easily into the sockets of an Arduino Esplora and an Arduino Robot. TFT LCD modules provide This technology is used in thin-film transistor liquid crystal display modules, or TFT LCDs. TFT technology allows for a full RGB display of a wide range of colours and hues. For vivid graphics, finely detailed images, and rich colours, choose an LCD with a TFT screen

TFT LCD (TFT liquid-crystal display) is a type of liquid-crystal display that uses thin-film transistor technology to improve image qualities such as addressability and contrast. A TFT LCD is an active matrix LCD, as opposed to a passive matrix LCD or a few simple, direct-driven (i.e., segments directly connected to electronics outside the LCD) LCDs. TFT LCDs are found in a variety of appliances such as televisions, computer monitors, mobile phones, handheld devices, video game systems, personal digital assistants, navigation systems, projectors, and automobile dashboards.

LCD: Liquid Crystal Display; an increasingly common type of display panel (like TV, PC computer, Mobile phone screen, etc.) TFT: Thin film transistor, which controls the colour and brightness of the LCD"s pixels, none directly endanger the eyes.

TFT displays motion more smoothly and responds more quickly than a monochrome LCD panel. TFT displays are bit expensive compared to monochrome LCD panels since they consume more electricity when operating.

TFT is a type of LCD that uses thin film transistor technology to improve image quality, whereas an LCD is a type of display that uses the modulating properties of liquid crystals to form what we call an LCD (liquid crystals display), which does not directly emit light.
