In a previous post Micro:bit and Cube:bit 'says' Hello I introduced the start of me playing with the 4tronix Cube:bit. One of the things I want to try is get the cube to react to music, based around the accelerometers in a micro:bit picking up vibrations. Luckily, in an earlier post, I had done something similar for the Proto-Pic Micro:pixel (see Dancing Pixels for more details).
Essentially the idea is the vibrations from the music shake the micro:bit enough to give measurable changes in three axis, and these values are used to change the pixel's colour - in fact five pixels at a time.
The code shown below is all that was needed:
from microbit import *
import neopixel, random
np = neopixel.NeoPixel(pin0, 125)
for pxl in range (2,125, 5):
np[pxl] = (rd, gr, 0)
np[pxl-1] = (rd, gr, 0)
np[pxl+1] = (0, gr, rd)
np[pxl-2] = (rd, 0, 0)
np[pxl+2] = (0, gr,0)
Here it is in action:
