FastLED Basics Episode 6 - Noise

In the 6th episode of FastLED basics, we look at the noise functions. These can be somewhat difficult to understand and there isn’t really any documentation to speak of. Noise provides a ’smooth randomness’ that allows plenty of interesting-looking patterns with only small amounts of code - if you know how to use it! CORRECTION: Around 16:15, I should have said that the last parameter in nblend is the amount of the second array to blend with the first from 0 (0%) - 255 (100%). I got mixed up with the fadeToBlackBy function above it.
