Steps

1. Connect the LCD module pins to your Arduino following the connection table.
2. Install the required libraries through the Arduino IDE library manager.
3. Load a sample sketch to test the LCD and ensure everything works correctly.
4. Configure the touch screen using the Adafruit_Touchscreen library or similar.
5. Design a custom screen with icons, buttons, and images.
6. Add logic to your project to interact with the LCD and touch screen.
7. Test your user interface to ensure everything works as expected.
8. Further customize your project by adding new features.

Example code

// Esempio di codice base
#include <Adafruit_GFX.h>
#include <Adafruit_ILI9341.h>
#include <TouchScreen.h>

#define YP A2 // Yellow wire on the touch screen
#define XM A0 // Blue wire on the touch screen
#define YM 5 // Green wire on the touch screen
#define XP 6 // Red wire on the touch screen

int joy_x_pos = 0; // horizontal position of joystick
int joy_y_pos = 0; // vertical position of joystick
TouchScreen ts = TouchScreen(XP, YP, XM, YM);
Adafruit_ILI9341 tft = Adafruit_ILI9341(TFT_CS, TFT_DC, TFT_RST);

Mini project

Create a small digital clock with an interactive display that shows the time and date. Add a function to set the time via the touchscreen.
