Code related to my Unicorn HAT tinkering
A CheerLights christmas tree on you UnicornHAT. Operates in one of 3 modes
- 0 = All; the tree is a mosaic of the past colours
- 1 = Lights; the main part of the tree is green with 5 lights and the star controlled by #cheerlights
- 2 = Star; just the top pixel changes to the most recent
Note: modes 1 and 2 swaps the colour green for yellow otherwise you wouldn't see it!
