Ok so I have one rigged up in my car just to test it, not to much to add but here is a video of it. I will be using 3 atmega’s to run them, since I need hardware spi and there is only one per atmega, so 2 to run the lights and one more to receive commands to change modes.
Also I am using one resonator to run both megas that are running the lights so when in ‘car show’ mode they will stay in sync with each other.
