3. What if Adafruit libraries are not displaying with the desired colors. This is a little hard to solve. Our suggestion, create a small function that display each color and note the number. Affordable electronics require a little more hacking, that"s all, it"s part of the fun. Check the following colors first, and adjust accordingly.

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.

For this tutorial I composed three examples. The first example is distance measurement using ultrasonic sensor. The output from the sensor, or the distance is printed on the screen and using the touch screen we can select the units, either centimeters or inches.

The next example is controlling an RGB LED using these three RGB sliders. For example if we start to slide the blue slider, the LED will light up in blue and increase the light as we would go to the maximum value. So the sliders can move from 0 to 255 and with their combination we can set any color to the RGB LED,  but just keep in mind that the LED cannot represent the colors that much accurate.

The third example is a game. Actually it’s a replica of the popular Flappy Bird game for smartphones. We can play the game using the push button or even using the touch screen itself.

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.

As the code is a bit longer and for better understanding I will post the source code of the program in sections with description for each section. And at the end of this article I will post the complete source 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.

Next we need to define the fonts that are coming with the libraries and also define some variables needed for the program. In the setup section we need to initiate the screen and the touch, define the pin modes for the connected sensor, the led and the button, and initially call the drawHomeSreen() custom function, which will draw the home screen of the program.

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.

Next is the distance sensor button. First we need to set the color and then using the fillRoundRect() function we will draw the rounded rectangle. Then we will set the color back to white and using the drawRoundRect() function we will draw another rounded rectangle on top of the previous one, but this one will be without a fill so the overall appearance of the button looks like it has a frame. On top of the button we will print the text using the big font and the same background color as the fill of the button. The same procedure goes for the two other buttons.

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.

drawDistanceSensor(); // It is called only once, because in the next iteration of the loop, this above if statement will be false so this funtion won"t be called. This function will draw the graphics of the first example.

getDistance(); // Gets distance from the sensor and this function is repeatedly called while we are at the first example in order to print the lasest results from the distance sensor

So the drawDistanceSensor() custom function needs to be called only once when the button is pressed in order to draw all the graphics of this example in similar way as we described for the home screen. However, the getDistance() custom function needs to be called repeatedly in order to print the latest results of the distance measured by the sensor.

Here’s that function which uses the ultrasonic sensor to calculate the distance and print the values with SevenSegNum font in green color, either in centimeters or inches. If you need more details how the ultrasonic sensor works you can check my particular tutorialfor that. Back in the loop section we can see what happens when we press the select unit buttons as well as the back button.

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:

drawDistanceSensor(); // It is called only once, because in the next iteration of the loop, this above if statement will be false so this funtion won"t be called. This function will draw the graphics of the first example.

getDistance(); // Gets distance from the sensor and this function is repeatedly called while we are at the first example in order to print the lasest results from the distance sensor

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:

https://www.anrdoezrs.net/links/7251228/type/dlg/sid/UUmuoUeUpU43826/https://www.youtube.com/supported_browsers?next_url=https%3A%2F%2Fwww.youtube.com%2Fwatch%3Fv%3DIcIY2pWursc

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?

The Radios, ILS and TACAN displays are all seven segment displays using the MAX7216 chip, purchased cheap on eBay, and run by Arduino and DCS-BIOS. They are all red in color because green seems to be four times the price. The larger displays that require more than just numbers, like the CMSP and CMSC, are 20x2 character OLED displays. You can shorten the character display and use a cheap 16x02 LCD, however I decided to spend a little more on those panels so i could fit all the characters in. The OLED displays are white, and some green cellophane material is put over the top to give them a green tint.

I"m not a programmer or coder, and nearly all of the code I used was cut and paste from ED forum members sharing their own work. The code that is mine is modifed from other users work, and is VERY untidy because I have no real idea what I am doing, but it works.

Very early on in the design process I decided I wanted to use a singe large display to cover the largest section of my Main Instrument panel. This is large enough to cover both MFD"s as well as all the gauges on the main panel. That meant I didn"t have to build complex servo or stepper motor driven gauges, and could just export them to the screen using Helios.

The main display is an LG 27MP3HQ-B. It is a discontinued model now, but at the time it was the cheapest 27 inch LCD IPS panel that I could find. It cost me $190 AUD ($144 USD). An OLED model would probably look much better with proper deep blacks, but I wasn"t willing to spend top dollar on an OLED monitor just to hack it up.

I removed the panel from its plastic casing (voiding its warranty) so it was smaller and thinner and mounted it"s control panel in the rear of my MIP.

It is connected to the PC via a HDMI cable. Both of the MFD"s, the Digital Clock, UHF repeater and the RWR display are exported in DCS World as viewports using edits to the Monitor Config .lua.

Here is the LG 27 inch monitor mounted in the center console. In this photo it still has its plastic casing on. I later removed this, to allow the screen to be about 3mm closer to the frame, and so there would be more room to run cabling behind it.

Here is the IPS Panel removed from the monitors plastic casing. Four screws and some plastic clips and it comes apart easily. I was happy to find that the ribbon cable to the PCB was long enough to allow me to mount it away from the panel.

This photo was taken when I was fitting the new custom MFD"s. You can see how the edge of the MFD is the very edge of the panel. You can also see how removing the plastic case of the panel allows for room to run cabling from the MFD around its edge and to a card mounted behind it.

The Main Instrument Panel fitted and working. It covers most of the main panel, however you can see how I had to make the fuel gauge and flaps gauge as it is not wide enough to cover the entire thing. One of the drawbacks is that the screen covers behind the AHCP, so I needed to space it out away from the panel to fit the switches.

Version one of my CDU was designed to fit this 5inch LCD HDMI Display Module, that I purchased from Buydisplay.com for around $33 USD. It was connected to the PC via a HDMI cable, and the CDU display was exported straight from DCS World using a viewport, just like the MFD"s.

This worked fine while I was using two projectors with a 180 degree screen, but after the addition of a third projector and the 270 degree screen upgrade, I was forced to remove the HDMI cable for the CDU as my PC has a maximum output of four monitors. This is a limitation of the software, as although I could in theory attach more monitors, NVIDIA surround wont let you combine more than four monitors as a single display, which meant in turn I was unable to warp and blend them on the curve. So four it is, three for the projectors and one for the MIP LCD.

I ran without a CDU display for a few months, before I eventually purchased this 3.5 inch TFT that is designed to push straight into an Arduino Nano. The CDU was very easy to export using DCS-BIOS, as a ED forums user has already done all the hard work for me. All I did was cut and paste the code, and it worked straight away. It has one minor drawback, being that the screen refresh rate is very slow, line by line. I actually like that, adds to the analog feel.

Here is the rear of version on of the CDU, with its breakout panel mounted. Ribbon cable connects the LCD to a control card that was mounted in the left console, and a HDMI cable attaches to that to the PC.

I added some small white markings to show where the lines of the smaller display are. This is because the OSB buttons were designed and positioned for the larger 5 inch LCD, and rather than redesign the entire thing to reposition the buttons I added these to make it easier to see which OSB activated which line on the display.

For the Counter Measure Systems Panel (CMSP) I used an OP2020i OLED display I purchased direct from the manufactuer wide.hk via their eBay store. Cost is around $38 AUD ($29 USD).

This is connected to an Arduino Uno, and I managed to modify some code that was posted on the ED forums for a 20x02 LCD display to get it to function on the OLED.

The CMSC complete. The "No Data Link" display was added by me into the Arduino Code. The display will show this when DCS-BIOS is not running, so I can tell by a glance that the display is actually working before I fire up the game. The OLED is white, and I later added a bit of green cellophane material on top to get it to match the rest of the cockpit.

The rear of the CMSC. You can see the Arduino Uno mounted. The small PCB is a breakout card i made up, just to distribute 12 volt power to the backlight circuit. The Uno is powered direct over USB.

It uses the same OP2020i OLED display and I designed and modified the panel with a bit of artistic license. The top panel covers the unused parts of the display to make it seem like its three small displays, like the real thing, father than one large one.

This display is run by an Arduino Mega that is mounted behind the MIP, with all the buttons and pots on it run by a separate Leo Bodnar Card also mounted behind the MIP.

The rear of the CMSC. The Op202i display had a plug soldered to it to allow for easy removal, as the Arduino is mounted remotely behind the MIP, so i would need to disconnect it if i need to remove the panel.

A view of the prototype PCB I soldered up to allow the backlight, buttons and warning LED"s to be mounted easily. The Warning LED"s are run by the same Arduino Mega mounted behind the MIP.

The display connected and working, with cellophane on top to dim and make it green. This display is actually broken, hence the dead pixels in the text. My fault- I dropped it and it shattered. It was replaced later on.

The Instrument Landing System (ILS) and TACtical Air Navigation System (TACAN) panel displays are run using seven segment displays, mounted on these MAX7219 8 Digit Seven Segment Display Modules.

Again, some artistic license was used on the panel so the top layer covers the unused sections of it and makes it look like it is separate displays, similar to the real jet.

Here is the MAX7619 eight digit seven segment displays that I used for the Radios, ILS and TACN panels. They are found on eBay or Aliexpress for around $5 AUD, and are very simple to code using DCS-BIOS. They come in differerent colours but all do the same thing.

I recommend using these ones, that have removable display modules rather than ones soldered direct to the board. This allows the PCB to be further away from the rear of you panel, which can assist with having enough space to mount buttons and switches closer to the display. It also allows you to remove the module and connect different displays, like I did for the radio stack below.

The ILS and TACAN panels are designed as one unit, so they can share a single Arduino Nano to run both displays. I designed the TACAN X/Y indicator to partially cover the display, and the code displays a zero depending on which mode is selected. This is because due to the design of a seven segment display, they cant show an X or Y.

ILS Panel in testing. I highly recommend adding add some sort of cover on these displays, as they are very hard to read without any filter. I added a peice of window tiniting film on top, which dims the segments that are not lit up making it easier to read.

The rear of the ILS and TACAN unit. A single Arduino Nano is mounted in a shield that runs both displays and the test light. All the buttons and switches are run from a seperate Leo Bodnar in the console.

I added the dashes to the code to be displayed when DCS-BIOS is not sending any data, so i can tell by a glance that the display is actually working when i turn it on.

The radio stack includes the UHF and two VHF"s and uses the same MAX7219 seven segment display modules as the ILS and TACAN. The top panels are again designed to cover the unused sections of the modules, to make it seem like they are individual displays.

The the preset channel indicators share a single MAX7219 card, and I removed the four digit display modules and soldered up pairs of individual segment displays onto some prototype PCB.

This is because the MAX7219 module PCB would not fit directly behind the panel like the frequency displays, as it would foul on the rotary switches and encoders next to them.

Here is the radio stack with the frequency displays mounted. You can see how the full displays have room to fit, however using individual the present channel displays are smaller and the PCB would not fit as they would hit the buttons and switches on either side.

Here is the prototype PCB with individual displays mounted. This allowed me to run cables from each preset display down to the MAX7219 PCB, which i mounted away from the panel.

This photo is a good example of how the displays are very hard to read at a glance without some sort of filter being placed on top. I added some window tinting film.

Another photo showing the difference in readability of the seven segment displays without a filter. In both photos the displays are showing the same thing. On the right I am holding a clear peice of acrylic with the protective plastic still on it over the top.

With the release of DCS World A-10C II Tank Killer, the Warthog is gaining an ARC-210 Digital Radio, and the top VHF module has been removed. I have already cut the top radio off, and designed and built my ARC-210. At the time i printed this, the radio hasn"t actually been released yet and is just a blanking plate.
