Clover drone kits contain addressable LED strips based on *ws281x* drivers. Each LED may be set to any one of 16 million possible colors (each color is encoded by a 24-bit number). This allows making the Clover flight more spectacular, as well as show flight modes, display stages of current user program, and notify the pilot of other events.

3. Configure the *ws281x* parameters in `~/catkin_ws/src/clover/clover/launch/led.launch`. Change the number of addressable LEDs and the GPIO pin used for control to match your configuration:
```xml
<param name="led_count" value="30"/> <!-- Number of LEDs in the strip -->
<param name="gpio_pin" value="21"/> <!-- GPIO data pin -->
<arg name="led_count" default="58"/> <!-- Number of LEDs in the strip -->
<arg name="gpio_pin" default="21"/> <!-- GPIO data pin -->
```
High-level interface allows changing current effect (or animation) on the strip. It is exposed as the `/led/set_effect` service. It has the following arguments:
