//***************************************************************
// Example to turn some pixels virtually "off" with a button.
// Pixels are still powered and reciving data, but are simply
// set to display black when "off".
//
// This example is for a 32 pixel strip.  Pressing the button
// turns "off" the last 8 pixels.  The pixel number where the
// cutoff starts is determined in the for loop on line 93.
//
// This is how the button is wired for this example:
// http://i.imgur.com/hOgQwjX.jpg
//
// Instead of a momentary button a switch could be used and
// the controller could directly read the input pin as high
// or low.  The button library would not be needed in this case.
