Chapter 5 of KitiBot-Microbit
RGB LED
There are 4 RGB LEDs on control board, you can program to control their colors. This chapter we learn how to control the RGB LED.
【Note】The neopixel library of micro:bit is conflict with Bluetooth. We use APA102 type RGB LED instead of WS2812 to avoid of conflict.
Create a new project, click Advance->Add Pakcages, input the address: https://github.com/waveshare/pxt-APA102 To add APA102 library. Affter adding, a new class APA102 can be chosen in Blocks area.
1. Lighting all RGB LEDs
First initialize APA102, set 4 LEDs as RGB, and save it to variable item.
Note: Control board use P8 and P12 to control RGB LED by default, if you change them, you need to set control pins
You can also set the color with this block
Download our demo code, 4 RGB LED will all light on.
2. Display different color
We try to change the code above and set 4 RGB LED display different colors separately
With this block, we can set pixel color from 0.
And show it. Without this block, the color you set before could not be showed.
