Thanks very much for FastLED. And the Fire2012 function (thx Mr. Kriegsman!)- very nice animation. I used it in a successful wearable, and needed to have two zones run from the same controller. A 8Mhz Arduino pro mini was a bit weak, but 16Mhz+ worked well. We eventually went with the Teensy 3.1.
I thought I’d share the code we used to generate the dual-zone animation for others to use. We tweaked the Fire2012 function to accept separate database arrays for it work with. It’s been successfully tested with up to 4 arrays so far.
