FAQ
Q: Why are you using the 4 pins? Can you direct me to a sketch to
test this out? I'm still trying to experiment with fastLED. I have a
Wemos D1 Mini. Wired up 5v and ground to the Wemos, Data in to D1 and
nothing to data out (?)
A: There is no need to connect data out if
you just use 1pcs RGB Right. But if you need connect several pcb
RGB ring, then you need connect the data out. Please check this tutorial
