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.

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:

Hello everyone to my new tutorial in which we are going to program arduino for tft lcd shield of 3.5" with ILI9486 driver, 8 bit. I found it important to write this tutorial as if we see we find tutorial for 1.44, 1.8, 2.0, 2.4, 2.8 inch shields however there are no or less tutorials available for 3.5" shield as its completely different from other smaller tft lcd shields -adafruit tft lcd library doesn"t even support ILI9486 driver in 3.5" tft lcd, it supports drivers of tft shields lesser then 3.5"

Go through the above link to know better, lets start with our tutorial however if we can"t use Adafruit_TFTLCD library which library will we use ?, there"s a simple answer to this that"s MCUFRIEND_kbv library which helps to use 3.5" tft lcd shield, if you see this library makes it much more easier to program arduino for tft lcd shield than adafruit as we have to simply create a tft object in MCUFRIEND_kbv library and then using that we can control the tft lcd shield however in Adafruit_TFTLCD library we will have to create the object and also define connections which makes it a very long task.

Once added, create the tft object using library name and a name for object, you can also define some color codes for text which we are going to type, using the define function and giving color code. This all is to be done before setup.#include#include#define BLACK 0x0000#define RED 0xF800#define WHITE 0xFFFFMCUFRIEND_kbv tft;

Its time to now start our tft lcd screen and change the background, this is to be done by using some simple functions by obtaining the tft ID and changing the background bytft.fillScreen("color_name");void}

Now we will be programming in loop for printing text on TFT LCD shield, for that we will be using a number of functions such as -tft.setCursor("x","y");x means the position from the x axis on screen and y means position from the y axis on screen of tft lcd shield.tft.setTextSize("number");number here refers to text size which take parameter as number you can give any number from 1 according to your requirements.tft.setTextColor("color");color here means to give the color name we had defined before setup, this makes the text color as whatever you give.tft.print("value");value is nothing but what you want to print, whatever you give as value must be in double quotes.void loop() {// put your main code here, to run repeatedly:tft.setCursor(0,0);tft.setTextSize(3);tft.setTextColor(WHITE);tft.print("my first project with tft -");tft.setCursor(0,70);tft.setTextSize(2);tft.setTextColor(RED);tft.print("welcome to the world of arduino and display , myself I love arduino and game programming very much. This is why I have my own youtube channel in which I share my arduino projects and games made by me , isn"t it amazing !");}

Graphics which we see in our phone is combination of square, rectangle, circle, triangle, lines. This is why here we will learning how to draw the following shapes.tft.drawRect(x,y,width,height,color);x means the position from the x axis of the screen, y means the position from y axis of the screen, width refers to set the width of rectangle, height refers to set the height of the rectangle and color means the color of rectangle you want it to be. You can use this same function by simply keeping the height and width same.tft.drawCircle(x,y,radius,color);x means the position from the x axis of the screen, y means the position from y axis of the screen, radius is a para to set the radius of circle and color means the color of circle you want it to be.tft.drawTriangle(x1,y1,x2,y2,x3,y3,color);x1, y1, x2 etc. are to set the position of triangle"s three points from which lines are drawn.tft.drawLine(x1,y1,x2,y2,color);x1 and y1 are to set point 1 from which line is made to point 2 which is set by x2 and y2.

Displaying a custom image or graphic on a LCD display is a very useful task as displays are now a premium way of providing feedback to users on any project. With this functionality, we can build projects that display our own logo, or display images that help users better understand a particular task the project is performing, providing an all-round improved User Experience (UX) for your Arduino or ESP8266 based project. Today’s tutorial will focus on how you can display graphics on most Arduino compatible displays.

The procedure described in this tutorial works with all color displays supported by Adafruit’s GFX library and also works for displays supported by the TFTLCD library from Adafruit with little modification. Some of the displays on which this procedure works include:

While these are the displays we have, and on which this tutorial was tested, we are confident it will work perfectly fine with most of the other Arduino compatible displays.

For each of the displays mentioned above, we have covered in past how to program and connect them to Arduino. You should check those tutorials, as they will give you the necessary background knowledge on how each of these displays works.

For this tutorial, we will use the 2.8″ ILI9325 TFT Display which offers a resolution of 320 x 340 pixels and we will display a bitmap image of a car.

To demonstrate how things work, we will use the 2.8″ TFT Display. The 2.8″ TFT display comes as a shield which plugs directly into the Arduino UNO as shown in the image below.

Not all Arduino displays are available as shields, so when working with any of them, connect the display as you would when displaying text (we recommend following the detailed tutorial for the display type you use of the above list). This means no special connection is required to display graphics.

Before an image is displayed on any of the Arduino screens, it needs to be converted to a C compatible hex file and that can only happen when the image is in bitmap form. Thus, our first task is to create a bitmap version of the graphics to be displayed or convert the existing image to a bitmap file. There are several tools that can be used for creation/conversion of bitmap images including, Corel Draw and Paint.net, but for this tutorial, we will use the Paint.net.

Your graphics could also include some text. Just ensure the background is black and the fill color is white if you plan to change the color within your Arduino code.

Image2Code is an easy-to-use, small Java utility to convert images into a byte array that can be used as a bitmap on displays that are compatible with the Adafruit-GFX or Adafruit TFTLCD (with little modification) library.

Paste the bit array in the graphics.c file and save. Since we have two graphics (the car and the text), You can paste their data array in the same file. check the graphics.c file attached to the zip file, under the download section to understand how to do this. Don’t forget to declare the data type as “const unsigned char“, add PROGEM in front of it and include the avr/pgmspace.h header file as shown in the image below.  This instructs the code to store the graphics data in the program memory of the Arduino.

With this done, we are now ready to write the code. Do note that this procedure is the same for all kind of displays and all kind of graphics. Convert the graphics to a bitmap file and use the Img2code utility to convert it into a hex file which can then be used in your Arduino code.

To reduce the amount of code, and stress involved in displaying the graphics, we will use two wonderful libraries; The GFX library and the TFTLCD library from Adafruit.

The GFX library, among several other useful functions, has a function called drawBitmap(), which enables the display of a monochrome bitmap image on the display. This function allows the upload of monochrome only (single color) graphics, but this can be overcome by changing the color of the bitmap using some code.

The Adafruit libraries do not support all of the displays but there are several modifications of the libraries on the internet for more displays. If you are unable to find a modified version of the library suitable for your the display, all you need do is copy the code of the drawBitmap() function from the GFX library and paste it in the Arduino sketch for your project such that it becomes a user-defined function.

The first two are thex and y coordinates of a point on the screen where we want the image to be displayed. The next argument is the array in which the bitmap is loaded in our code, in this case, it will be the name of the car and the text array located in the graphics.c file. The next two arguments are the width and height of the bitmap in pixels, in other words, the resolution of the image. The last argument is the color of the bitmap, we can use any color we like. The bitmap data must be located in program memory since Arduino has a limited amount of RAM memory available.

As usual, we start writing the sketch by including the libraries required. For this procedure, we will use the TFTLCD library alone, since we are assuming you are using a display that is not supported by the GFX library.

Next, we specify the name of the graphics to be displayed; car and title. At this stage, you should have added the bit array for these two bitmaps in the graphics.c file and the file should be placed in the same folder as the Arduino sketch.

The last section of the code is the drawBitmap function itself, as earlier mentioned, to use the drawbitmap() function with the Adafruit TFTLCD library, we need to copy the function’s code and paste into the Arduino sketch.

Plug in your screen as shown above. If you are using any other display, connect it as shown in the corresponding linked tutorial. With the schematics in place, connect the Arduino board to your PC and upload the code. Don’t forget the graphics file needs to be in the same folder as the Arduino sketch.

That’s it for this tutorial guys. The procedure is the same for all kinds of Arduino compatible displays. If you get stuck while trying to replicate this using any other display, feel free to reach out to me via the comment sections below.

Let"s get started with this creative Arduino project, where you"ll learn about the TFT LCD touch screen and how to use it to create your own colourful calculator. For a basic understanding of touch screen & LCD, a cheap TFT 2.4" Arduino shield is used to create this project. For creating a similar project, one should follow the steps and edit the code for better understanding.

The shield connects ILI9341"s data pins 0-7 to Arduino"s digital pins 2-8 (allowing parallel communication, not SPI. ILI9341"s RESET goes to Arduino analog pin A4. CS (chip select) to A3. RS (CD command/data) to A2. WR and RD to A1 and A0.

To install this library, you can simply click on the link above which will take you to a Github page. There click on clone or download and select “Download ZIP”. A zip file will be downloaded.

Now, open Arduino IDE and select Sketch -> Include Library -> Add .ZIP library. A browser window will open navigate to the ZIP file and click “OK”. You should notice “Library added to your Libraries” on the bottom-left corner of Arduino, if successful.

You can also find an SD card slot at the bottom of the module shown above, which can be used to load an SD card with BMP image files, and these images can be displayed on our TFT LCD screen using the Arduino Program.

The 2.4” TFT LCD screen is a perfect Arduino Shield. You can directly push the LCD screen on top of the Arduino Uno and it will perfectly match with the pins and slid in through. However, as matters of safety cover the programming terminal of your Arduino UNO with some insulator, just in case if the terminal comes in contact with your TFT LCD screen.

The shield is fully assembled, tested, and ready to go. No wiring, no soldering! Simply plug it in and load up the library - you"ll have it running in under 10 minutes!

This library is the continuation of my ITDB02_Graph, ITDB02_Graph16 and RGB_GLCD libraries for Arduino and chipKit. As the number of supported display modules and controllers started to increase I felt it was time to make a single, universal library as it will be much easier to maintain in the future.

Basic functionality of this library was origianlly based on the demo-code provided by ITead studio (for the ITDB02 modules) and NKC Electronics (for the RGB GLCD module/shield).

The library works great with the ITDB02 series of display modules from ITead Studio, the TFT01 series of display modules from ElecFreaks, and the RGB LCD Shield and module from NKC Electronics.

Due to the size of the library I do not recommend using it on ATmega328 (Arduino 2009/Uno) and ATmega32U4 (Arduino Leonardo) as they only have 32KB of flash memory.
