I spent a few hours last night and like six hours today getting this together. Totally worth it.
Sometime later I’d like to add a few of my own color patterns, but this is good for now. I’d like to have a mode that comes closer to simulating “christmas tree lights” – lone sparkles in a mostly-dark strip. I have ideas of how to make it happen.
It’d also be nice to have two more buttons so I can turn random mode off; I don’t have any more buttons in my electronics box right now. So I deal.
Code from here. It worked like a charm once I went deep inside the code and told it which pins to use for input and output. But getting to that point took an annoying amount of time, as usual.
(If you want to make one of your own, you may also want to go into LEDStripG35String.cpp and change line 10 to LEDStrip8806 strip = LEDStrip8806(numPixels,[your data line],[your clock line]);, and change the pin list in the definition of ‘buttons’ in LEDStripXmas.ino to match your wiring.)
