The PiGlow Python library makes controlling PiGlow a piece of cake. You can control the brightness of the different colour groups of LEDs, the arms of the nebula, or individual LEDs – flexible! There’s also a handful of examples to show you what can be done.
A bunch of awesome folk have contributed code for PiGlow. Here’s just some of it:
