Our neighborhood does this thing where everybody outlines their yard in white AC mini bulbs. I'm adding pixels to our roofline this year, and need a way to turn the AC yard lights off during the show. It only consists of 3 strands daisy-chained, so I don't see any real reason to invest in a multi-channel controller, because all but 1 channel would go unused.
Btw, for the pixels, I'm using a Pi3 and Falcon PiCap.
What are your recommendations?
