tft lcd touch 2.4 shield para arduino mega factory
This is the 2.4 inch touch screen for Arduino UNO and MEGA. It use 8-bit parallel bus, faster than serial SPI refresh , support 16-bit RGB 65K color display, display rich colors , easy to expand the experiment with SD card slot.
Voltage type: 5v or 3v voltage input voltage,input is selectable. Because TFT can only work under 3.3 V voltage, so when the input voltage VIN is 5V, need through the 3.3 V voltage regulator IC step down to 3.3V , when the input voltage of 3.3 V, you need to use the zero resistance make J2 short , is equivalent to not through the voltage regulator IC for module and power supply directly.
In most of the Arduino projects, it would be extremely delighted to have a display through which we can monitor the vitals of our project. 2.5 Inch TFT LCD Touch Screen for Arduino display module designed specifically for Arduino UNO, and also supports working on Arduino 2560 MEGA MCU Board. This module adds a touch up to your Arduino project with a beautiful large touchscreen display shield with a built-in microSD card connection.
This 2.5 Inch TFT LCD is a colour active matrix TFT liquid crystal display with a resistive touch screen. The TFT display provides a resolution of 240×320 pixels with individual pixel control, thus providing a better display. It offers more resolution than a black and white 128×64 display. This 2.5 Inch TFT LCD Screen display has an ILI9341 controller IC which supports MCU Interface. A 4-wire XPT2046 resistive touchscreen is attached to the display, so we can detect finger presses anywhere on the screen.
The ILI9341 is a 262,144 colour single-chip SOC driver for the TFT liquid crystal display. It provides a resolution of 240RGB 320 Dots, comprising a 720 channel source driver, a 320 channel gate driver, 172800 bytes GRAM for graphic display data of 240 RGB x 320 dots, and a power supply circuit. These ILI9341 Chip can operate at an interface voltage of 1.65v to 3.3v. And an incorporated voltage follower circuit is used to generate voltage levels for driving an LCD.
Moreover, It supports the FBCP software driver, allowing it to configure software resolution, and set up dual-display. These display modules are mounted with high-quality immersion gold surface plating. This Touch Screen Module shield with Micro SD slot especially for UNO and MEGA, driven by ILI9341 Single Chip Driver. The shield connects ILI9341’s data pins 0-7 to Arduino digital pins 2-8 (allowing parallel communication, not SPI). And ILI’s RESET goes to pin to Arduino analogue pin A4.CS (chip select) to A3. RS (CD command/data) to A2. WR and RD to A1 and A0.
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 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.
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.
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:

This is a versatile and Arduino/Seeeduino/Arduino Mega compatible resistive touch screen shield which can be used as display device, or sketch pad for user input/interface.
Compared with the previous version (2.8" TFT Touch Shield V1.0) we improved the screen driver with a professional chip (ILI9341) to provide the pin-saving SPI communication protocol without sacrificing the data transmission speed.
Circles isn"t the only thing our library can help you draw, we also have a lines, number, rectangle, and many more examples. Check those out as well to become a pro with the shield.
Function Description: The drawCircle function draws an empty circle with the center at the coordinates poX, and poY. The circle will be of radius r and the border color will be color. The color parameter is a 16-bit Red-Geen-Blue (RGB) integer, in the example code above the words YELLOW, CYAN, RED, and BLUE are defined as integers in the TFTv2.h file.
The TFT Touch Shield"s backlight is on by default since its control circuit is directly powered by the 5V pin. If, however, you wish to control the backlight"s on/off state using the Arduino Digital I/O pin 7, a simple modification will have to be made:
Now controlling the backlight"s state is as easy as controlling an LED, upload the following code to the Arduino board to see how to toggle the backlight every 500ms (1/2 second):
I still remember when I post my first Instructable post years ago, it"s a project about Arduino, I made a phone with Arduino. It"s called ArduinoPhone, even today I can get some comments from it, and I am glad to help others to make their own phone with Arduino.
Combining Arduino and other shield modules, we make a mobile phone named Arduino Phone. Meanwhile, we printed a shell for it with the 3D printer. Although it"s not such fine as you think, even a little bit clunky, it"s still very cool. That is the point this is a cell phone made by ourselves.
While, we can"t install Arduino Phone Apps limited by Arduino. So, if you want to play Angry Birds, then you need to do some big modifications on Arduino Phone. :)
