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) while True:     for pxl in range (2,125, 5):         rd=int(abs(accelerometer.get_x())/20)         gr=int(abs(accelerometer.get_y())/20)   ...
