What it is for

Ideally fits to create a control display on drones or other projects that require a clear real-time data display such as altitude and speed.

Tutorial: How to use 4.3 inch Auto TFT LCD Screen

The 4.3 inch TFT LCD screen is ideal for displaying PAL/NTSC video on drones and other projects that require clear resolution and wide view.

What you need

• Arduino Uno
• USB Type B cable
• Jumpers

Steps

1. Connect the TFT LCD screen VCC pin to Arduino Uno VCC pin
2. Connect the screen GND to Arduino Uno GND
3. Connect the following pins: SCLK, MOSI, MISO, CS, DC, RES and RST of the screen to the corresponding pins of the Arduino Uno (check the datasheet)
4. Install the TFT_ILI9341 library from managed libraries
5. Write a simple sketch to initialize the display
6. Test the test image on the display
7. Check that all connections are correct and stable
8. Modify the sketch to add text or images

Example code

void setup() {
  tft.begin();
  tft.fillScreen(TFT_BLACK);
}

void loop() {}

Mini project

Create a control display for drones with the TFT LCD, showing data such as altitude and speed in real-time.

Common mistakes

• Unstable or reversed connections
