Rgb Light Test - Keyestudio Micro:bit Mini Smart Robot Car V2 Instructions Manual

RGB Light Test

Description
There are two RGB lights on the robot shield. You will learn how to make
the two RGB lights as indicator for the micro:bit robot. To save the IO port
resources, we will use a PCA9685PW chip to drive the two RGB lights.
In the circuit, Pin LED 4 of PCA9685PW chip is used to control the blue
light of RGB; pin LED 5 controls the green light, while pin LED 6 controls
the red light.
In this lesson, you will learn how to drive the two RGB LEDs circularly light
up the red, green and blue light colors. Another one is to show different
color of light.
