These are what I use for all the lighting effects driven by the Pinduino. Ramp, playfield, backbox, toppers, etc. If you are curious, check out my Pinside store: https://pinside.com/pinball/market/shops/1025-professor-pinball
All my code is open source: https://github.com/elyons/professor_pinball_pinduino_sketches
People have made lots of great mods and lighting effects that are driven by the Pinduino.
