ROB0150 micro:bit Example Code: Rotated Circular Light

The 9 RGB LEDs display 9 colors (gradients), and then on the lamp ring the nine RGB LEDs display the 9 colors in a continuous loop just like a waterfall light. Modify the color behind the show color to get other solid color rotation effects.

Hardware Preparation

micro:bit main board ×1
ROB0150 24 RGB LEDs Circular Expansion Board ×1
(Purchase Link)
USB cable ×1

Software Preparation

Development Tool:
MakeCode
https://makecode.microbit.org
Add the Neopixel Software Package
Load the neopixel library to control the LED ring.

Other Preparation Work

Add the neopixel software package (loading the lamp ring library) in Makecode; the steps are as follows:

Add the software package

Sample Code

Click and enter the graphic programming: The Graphic Programming of Rotated Circular Light

Light up 9 LEDs from the No. 0 LED and the color range 0~255.

Set the brightness of the LED to 100

Set the rotation speed

For solid color rotation effect:

Click and enter the graphic programming：Yellow Rotating Circular Light

solid color

Result

Gradient rotation effect: The 9 RGB LEDs display 9 colors (gradients) in a continuous loop just like a waterfall light.
Solid color rotation effect: The 9 RGB LEDs display a solid color in a continuous loop.

Additional Information

Modify the color behind the "show color" block to get other solid color rotation effects.
