ESP32_examples

Examples prepared for workshop content. The examples are built for ESP32-WROOM-32E Dev Kit, ESP32-S3-DevkitC-1 and Arduino IDE. For setup of Arduino IDE for ESP32, visit Espressif Arduino Repository and Getting Started Guide.

Content

1. Basic LED

   • Push button once to toggle between on and off LED

2. LDR LED

   • When in dark environment, turn on LED, else off LED

3. Receiver LED

   • Receiver via Bluetooth Classic. When receiving '1', turn on LED. When receiving '0', turn off LED
   • Only for ESP32

4. Transmitter Button

   • Transmitter via Bluetooth Classic. When button press, send a signal to toggle LED on receiver
   • Only for ESP32

5. Transmitter LDR

   • Transmitter via Bluetooth Classic. When in dark environment, turn on LED, else off LED
   • Only for ESP32

6. BLE Client LED

   • Connects to BLE Server and receives updates via notifyCallback. When receiving '1', turn on LED. When receiving '0', turn off LED
   • Only for ESP32-S3

7. BLE Server Button

   • Connects to BLE Client and sends updates via notify. When the button is pressed, toggle the characteristic value to '1' or '0'
   • Only for ESP32-S3

8. Rainmaker switch and LDR

   • Runs Rainmaker. Collects LDR sensor data, and control LED from both app and device.
   • Only for ESP32-S3
   • Work in progress for compatibility with ESP32
