Data in, Not Out

While we didn’t have much success a couple of days ago, today we got the lights to work properly. Turns out, that I’ve made the beginner mistake number 1 when dealing with Neopixels — I connected the data signal from the Fadecandy to the DOUT pin of the LED strip (there’s also a DIN pin, at the other end of the strip).

I should have read the Digital LED Strip Read Me First first.
