What you need

• Arduino Mega
• USB A-Micro B cable
• Screwdriver set

Steps

1. Connect the TFT module to the Arduino Mega SPI pins (11, 13, 49-52).
2. Download the Adafruit GFX and Adafruit ST7735 libraries from the official website.
3. Include the libraries in your Arduino project.
4. Configure the display using the methods available in the library documentation.
5. Draw a rectangle or a line to check the connection.
6. Check that the display backlight is properly adjusted (check the datasheet).
7. Add text and images to your project.
8. Save the sketch file and upload it to the Arduino Mega.

Example code

// Includi le librerie
#include <Adafruit_GFX.h>
#include <Adafruit_ST7735.h>
// Configura l'oggetto display
Adafruit_ST7735 tft = Adafruit_ST7735(TFT_CS, TFT_DC);
void setup() {
tft.begin();
tft.fillScreen(ST77XX_BLACK);
tft.drawRect(0, 0, 160, 80, ST77XX_WHITE);}
void loop() {}

Mini project

Create an interactive digital clock that displays the time and date on the TFT display.

Common mistakes

• SPI pin connection error.
