Quoted from lyonsden:
Awesome work @dantesmark! Some people have already asked me for this kit. If you want to buy a plug and play kit, I just listed it: https://pinside.com/pinball/market/shops/1025-professor-pinball/01979-pinduino-white-water-interactive-lighting-for-the-ramps
For those that want to make it yourself, here are the instructions (thanks again, Dan for the pictures!): https://docs.google.com/document/d/1IhPxJX-rjk746d-eUyMkV-aTM7qvh0dUL39pcRxCexA/edit
Code (open source): https://github.com/elyons/professor_pinball_pinduino_sketches/blob/master/WhiteWater-LeftRamp/WhiteWater-LeftRamp.ino
Quick question. How do you speed up effect, so it tries to be in sync with ball.
You mentioned something about a switch at top of ramp. Does it come with kit, or separate purchase?
