/*
 
*  Serial control interface for LED Strip
 
*
 
*    Updated: 20140923
 
*
 
*      H4X0r'd some shitz uppple
 
*        -- insert LED of some sort in A0 & Ground (in right direction)
 
*        -- pseudo lite senzor for mode switching
 
*        -- pseudo lite mode 8 noise floor graph
 
*
 
*    Command Summary:
 
*      MODE0 == Auto (Rainbeau)
 
*      MODE1 == Off
 
*      MODE2 == Remote (PC Control)
 
*      HH..H == Sequence of Hue values to apply to LEDs
 
*        Note: Set "MODE2" before sending hues
 
*      S    == Set saturation
 
*      MODE3 == Center Peak Rainbeau
 
*      MODE4 == Center Peak Pastel
