 /************************************************************************************************************************************
 * ShiftPWM blocking RGB fades example, (c) Elco Jacobs, updated August
2012.
 *
 * ShiftPWM blocking RGB fades example. This example uses simple delay
loops to create fades.
 * If you want to change the fading mode based on inputs (sensors,
buttons, serial), use the non-blocking example as a starting point.
 * Please go to www.elcojacobs.com/shiftpwm for documentation, fuction
reference and schematics.
 * If you want to use ShiftPWM with LED strips or high power LED's,
visit the shop for boards.
