// Example showing how to use FastLED color functions
// even when you're NOT using a "pixel-addressible" smart LED strip.
//
// This example is designed to control an "analog" RGB LED strip
// (or a single RGB LED) being driven by Arduino PWM output pins.
// FastLED's ANALOG_RGB controller applies brightness, color correction, and
// color temperature before writing PWM duty cycles to the three output pins.
// 
// In this example, the RGB values are output on three separate
// 'analog' PWM pins, one for red, one for green, and one for blue.

#define GREENPIN 6
#define BLUEPIN  3

// Helpful for diagnosing if you've mis-wired which is which.
