Tutorial: How to use 2.8-inch TFT LCD screen with touch screen

This 2.8-inch TFT LCD screen with touch screen module is perfect for Arduino projects that require graphical visualization. Ideal for programming and electronics enthusiasts who want to add an intuitive user interface to their devices.

What you need

• Arduino Uno or compatible
• USB cable to connect Arduino to the computer
• Required Arduino libraries
• Arduino development software
• Head or breadboard connections
• Power supply for Arduino

Steps

1. Connect the LCD TFT display to the breadboard or head circuit.
2. Connect the display pins to the Arduino pins: check the datasheet for specific details.
3. Install the necessary libraries for the display and touch screen in Arduino.
4. Write an Arduino sketch that initializes the display and tests the touch screen function.
5. Upload the sketch to the microcontroller.
6. Verify that the display shows the correct text or image.
7. Test the touch screen to ensure it works properly.
8. Customize the sketch to integrate the display and touch screen into the project.

Example code

/*
  Sketch di esempio per il display LCD TFT 2,8 pollici con touch screen
*/
#include <Adafruit_GFX.h>
#include <Adafruit_ST7735.h>

// Inizializza il display
Adafruit_ST7735 tft = Adafruit_ST7735(TFT_CS, TFT_DC, TFT_MOSI, TFT_SCLK, TFT_RST);

void setup() {
  tft.begin();
  tft.fillScreen(ST7735_BLACK);
  tft.setCursor(0,0);
  tft.setTextColor(ST7735_WHITE);
  tft.setTextSize(2);
  tft.println("Benvenuto!");
}

void loop() {
  // Aggiungi qui il codice per il touch screen
}

Mini project

Create a digital clock with a graphical interface that displays the time and date. Add a menu to set the time and date.

Common mistakes

• Connection error between the display and Arduino pins.
• Forgetting to install the necessary libraries.
• Insufficient power supply issues.
• Difficulty in correctly configuring the touch screen.

Recommended accessories

• Arduino Uno
