# Arduino-ESP32 Zigbee Light Bulb Example
This example shows how to configure the Zigbee end device and use it as a Home Automation (HA) on/off light bulb.
Hardware Required
* One development board (ESP32-H2 or ESP32-C6) acting as Zigbee coordinator (loaded with Zigbee_Light_switch example)
* A USB cable for power supply and programming
* Choose another board (ESP32-H2 or ESP32-C6) as Zigbee end device (loaded with Zigbee_Light_bulb example)
.
By default, the `neoPixelWrite` function is used to
control the LED. You can change it to digitalWrite to control a simple LED.
#### Using Arduino IDE
* Before Compile/Verify, select the correct board: `Tools -> Board`.
* Select the End device Zigbee mode: `Tools -> Zigbee mode: Zigbee ED (end device)`
* Select Partition Scheme for Zigbee: `Tools -> Partition Scheme: Zigbee 4MB with spiffs`
* Select the COM port: `Tools -> Port: xxx` where the `xxx` is the detected COM port.

# Arduino-ESP32 Zigbee Light Switch Example
This example shows how to configure Zigbee Coordinator and use it as a
Home Automation (HA) on/off light switch.
**This example is based on ESP-Zigbee-SDK example esp_zigbee_HA_sample/HA_on_off_switch.**
# Supported Targets
Currently, this example supports the following targets.
| Supported Targets | ESP32-C6 | ESP32-H2 |
| ----------------- | -------- | -------- |
## Hardware Required
* One development board (ESP32-H2 or ESP32-C6) acting as Zigbee end device
(loaded with Zigbee_Light_bulb example).
* A USB cable for power supply and programming.
* Choose another board (ESP32-H2 or ESP32-C6) as Zigbee coordinator
(loaded with Zigbee_Light_switch example).
### Configure the Project
Set the Button Switch GPIO by changing the `GPIO_INPUT_IO_TOGGLE_SWITCH` definition.
By default, the LED_PIN is `GPIO_NUM_9`.
#### Using Arduino IDE
To get more information about the Espressif boards see
[Espressif Development Kits](https://www.espressif.com/en/products/devkits).
* Before Compile/Verify, select the correct board: `Tools -> Board`.
* Select the Coordinator Zigbee mode: `Tools -> Zigbee mode: Zigbee ZCZR (coordinator)`.
* Select Partition Scheme for Zigbee: `Tools -> Partition Scheme: Zigbee 4MB with spiffs`.
* Select the COM port: `Tools -> Port: xxx where the `xxx` is the detected COM port.
* Optional: Set debug level to info to see logs from Zigbee stack: `Tools -> Core Debug Level: Info`.Interruptor Zigbee
