An addressable LED animation for NeoPixels and the Particle Core/Photon. Spooky blinking eyes!
This is an LED strip animation which is supposed to resemble pairs of glowing eyes that appear, blink a few times, then disappear again. The idea is that the lights could be hidden in shrubbery, under a porch, behind a dark window, etc, to give the impression of sinister monsters watching from the shadows!
The animation is implemented as a reusable class. You can have multiple instances, each with their own settings, running simultaneously. The instances can be run on a shared NeoPixel strip instance, or you can have multiple NeoPixel instances driving multiple strips, each with their own set of eyeblink animations.
You can find more information in the Particle Community forums.
