Disco micro:pixel

In a previous post Proto-Pic board, Microbit and Micropython I played with the Proto-Pic micro:pixel 4x8 NeoPixel board. 

This post is just a short description of a quick play with making it flashing blocks of different colours across the board. The routine produces five random numbers (three to define the colours, one for which pixel is selected and the last for the delay each iteration). The idea of being - a pixel is selected, but so are the ones either side of it, each one has a different combination of the colour values, but only two of the pixels are turned off after the delay.

from microbit import *
import neopixel, random

# Setup the Neopixel strip on pin0 with a length of 2 pixels
np = neopixel.NeoPixel(pin0, 32)

while True:
    np[pxl] = (rd, gr, bl)
    np[pxl-1] = (gr, bl, rd)
    np[pxl+1] = (bl, rd, gr)
    np[pxl] = (0, 0, 0)
    np[pxl+1] = (0, 0, 0)

The video below shows the routine in action. There is no connection between the pixels and the music on the video - but making the connection between music and the pixels would be an interesting project.
