Sometimes its fun to build and code a little project to test new hardware, as well as just for the heck of it. I built this demo thing with a Spikenzie Labs SPLixel board and LED strip, Arduino, and ScrewShield. I read one knob to control the position (which LED is lit), the other controls the green component of the color mix.
In order to keep the knobs from moving around too much, I screwed some small c-clamps onto them.
It’s fun to play with. A little bit.
