Tutorial: How to use Touch LCD SPI TFT 2.8 inch Display Module

This 2.8 inch TFT touch display module is ideal for projects requiring an interactive graphical interface. It is perfect for makers who want to add colorful and touch-sensitive screens to their Arduino projects.

What you need

• Arduino Uno or compatible
• USB cable to connect Arduino to PC
• Jumper wires
• Third-party libraries to manage the display
• Arduino IDE development software
• Touch Screen Tester (optional)

Steps

1. Connect the display module to the Arduino SPI pin
2. Install the necessary libraries in the Arduino IDE software
3. Write a sketch to initialize the display
4. Test the display functionality
5. Configure the touch screen
6. Verify the correct interaction between display and touch screen
7. Try drawing simple shapes on the display
8. Add interactive features to the display

Example code

/* Includi le librerie necessarie */
#include <Adafruit_GFX.h>
#include <Adafruit_ILI9341.h>

/* Inizializza il display */
Adafruit_ILI9341 tft = Adafruit_ILI9341(TFT_CS, TFT_DC, TFT_MOSI, TFT_SCLK, TFT_RST);

void setup() {
  tft.begin();
  tft.fillScreen(TFT_BLACK);
  tft.setCursor(0,0);
  tft.setTextColor(TFT_WHITE);
  tft.setTextSize(2);
  tft.println("Benvenuto!");
}

void loop() {
}

Mini project

Create an interactive digital clock that displays the time and day of the week on the display and allows setting the time with the touch screen.
