1. Hardware Setup

   • Components Needed: • XIAO ESP32C3 • LED • Breadboard • Jumper wires • Circuit Connections: • Connect the longer leg (anode) of the LED to a GPIO pin (e.g., GPIO2). • Connect the other to GND.

2. Software Setup

   1. Install Arduino IDE: • Download and install the Arduino IDE from here.
   2. Add ESP32 Board Support: • Go to File > Preferences. • Add the URL: https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json • Open Tools > Board > Board Manager, search for ESP32, and install.
   3. Install Required Libraries: • Open Tools > Manage Libraries, and install: • ESPAsyncWebServer • ArduinoJson
   4. Upload the Code: • Use the code provided above. • Configure Wi-Fi credentials in the code. • Connect the board and upload the code via Arduino IDE.

3. How to Use

   1. Power the XIAO ESP32C3: • Connect the board to your computer or a power source.
   2. Connect to the Board: • Wi-Fi Mode: • Connect your phone to the board’s Wi-Fi network.
   3. Control the LED: • Use the application app to toggle the LED,which you can download the application in releases s4. Additional Notes

   • Ensure the XIAO ESP32C3 board is properly configured in Arduino IDE under Tools > Board. • Test the connections before powering on to avoid damage to components. • For troubleshooting, use the Serial Monitor in Arduino IDE.
