Hey guys, I figured I'd share my progress on a shift light I've been working on in case anyone was interested.
I'm using an Arduino to run the lights, another arduino to generate the RPM and a RaceCapture to display the current rpm.
This uses an encoder dial to change the brightness, colors, when the lights start and change, shift light modes, and etc. The program stores the changes you make into one of 5 different fully customizable saves. I can't take full credit for the coding, but I hope you enjoy it anyways!
