Hello all!
I am trying to write my own library (my first!) for using WS2812 LEDs with a IR remote.
I followed the Arduino tutorial on how to write an Arduino library, but their example is so simple!
I would like to utilize two other Arduino libraries, inside my own. Is this possible? I tried to do that, but I totally fudged it and it, of course, doesn't compile.
Any ideas?
Thanks in advance!
