# Light Switch Example 

(See the `README.md` file in the upper level 'examples' directory for more information about examples.)

This test code shows how to configure Zigbee end device and use it as a light switch

## Hardware Required

* One development board with ESP32-H2 SoC acting as Zigbee coordinator (loaded with light switch example)
* A USB cable for power supply and programming
* Choose another ESP32-H2 as Zigbee end-device (see [light bulb example](../light_bulb))

## Configure the project

Before project configuration and build, make sure to set the correct chip target using `idf.py set-target esp32h2`.

## Build and Flash

Build the project, flash it to the board, and start the monitor tool to view the serial output by running `idf.py -p PORT flash monitor`.

(To exit the serial monitor, type ``Ctrl-]``.)

## Example Output

As you run the example, you will see the following log:

## Light Control Functions

  * By toggling the switch button (BOOT) on this board, the LED on the board loaded with the `light bulb` example will be on and off.
