Project Details
How It Works
How It WorksESP32 initializes the TFT display and touch controller. When a user touches the screen, the touch controller detects the input and provides coordinates. These coordinates are mapped to screen positions, and the GUI logic responds by updating display elements or executing actions like controlling devices or displaying sensor data. The system operates independently without needing mobile apps.
Prerequisites
Basic knowledge of Arduino programming, understanding of SPI communication, familiarity with ESP32 hardware, and experience with basic electronics and circuit connections.
