/* FastLED RGBW with gamma correction over Perlin Noise
 *  
 *  By: Andrew Tuline
 *  
 *  Date: March, 2019
 *
 * Example sketch using FastLED for RGBW strips (SK6812) along with gamma correction.
 * 
 * The RGBW component was written by David Madison and originally by Jim Bumgardner.

 * Based previous work (namely twinklefox) by Mark Kriegsman, this program shows how you can fade-in twinkles by using the fact that a random number generator
 * with the same seed will generate the same numbers every time. Combine that with millis and a sine wave and you have twinkles fading in/out.

 *  Testing gamma correction to change LED brightness so that it appears to change evenly for the viewer. The problem is that changes above 
 *  50 are much less noticeable for the viewer, so the LED gets bright quickly and then stays bright for way too long before dimming again.
 *  
 *  There's a few ways to adjust LED output. The table method was proposed on Adafruit.com. Here's a couple of other methods for demonstration.

 *
 * Why use a 7 band MSGEQ7 graphic equalizer chip when you can get many times more frequency bins with software alone and on an Arduino UNO to boot?
 * 
 * This example combines high speed A/D conversion, FFT (Fast Fourier Transform) pitch detection combined with simple FastLED library display using

 * By: Andrew Tuline

 * Date: January 2019
 *
 * This uses the built in FastLED beatsin8 combined with a sinewave to move one or more pixels back and forth.
