Control RGB Light

1. API Introduction

The API for RGB light:

Arm_RGB_set(R, G, B)

Function: Set the color of the RGB light.

Parameters:

R: Controls the brightness of red color for the RGB light, range 0-255, higher value means brighter.

G: Controls the brightness of green color for the RGB light, range 0-255, higher value means brighter.

B: Controls the brightness of blue color for the RGB light, range 0-255, higher value means brighter.

Return value: None.
