# Switch Example
|
|
|
|
## Build and Flash firmware
|
|
|
|
Follow the ESP RainMaker Documentation [Get Started](https://rainmaker.espressif.com/docs/get-started.html) section to build and flash this firmware. Just note the path of this example.
|
|
|
|
## What to expect in this example?
|
|
|
|
- This example uses the BOOT button and RGB LED on the ESP32-S2-Saola-1/ESP32-C3-DevKitC board to demonstrate a switch.
|
|
- The LED state (green color) indicates the state of the switch.
|
|
- Pressing the BOOT button will toggle the state of the switch and hence the LED. This will also reflect on the phone app.
|
|
- Toggling the button on the phone app should toggle the LED on your board, and also print messages like these on the ESP32-S2 monitor:
|
|
|
|
```
|
|
I (16073) app_main: Received value = true for Switch - power
|
|
```
|
|
|
|
### LED not working?
|
|
|
|
The ESP32-S2-Saola-1 board has the RGB LED connected to GPIO 18. However, a few earlier boards may have it on GPIO 17. Please use `CONFIG_WS2812_LED_GPIO` to set the appropriate value.
|
|
|
|
### Reset to Factory
|
|
|
|
Press and hold the BOOT button for more than 3 seconds to reset the board to factory defaults. You will have to provision the board again to use it.
