I am wiring up some LED light strips to attach to a pinewood derby car. I want them to turn on and run a rainbow light run when acceleration is detected.
so far, I have code that runs the rainbow light sequence when it is run in isolation, and i have code that turns the LED strips on when it senses acceleration in the y axis. However, i have not had luck getting the two parts to play nice with each other. When running the code below, the LED's turn on, but it does not run the strips loop effect.
Thank you for your time,
Joey
