/*
Create an array of values to control each LED NODE in the standard RadioShack strip.
  
PROGMEM will assign values to store in the AVR chip's RAM memory as a two dimensional array.
  
We will then read out these values to create a serial pulse train OUTPUT to the LED Strip.

Each ROW is sent as OUTPUT and will SET the COLOR for each of the TEN (10) nodes .  

Each ROW is a NEW FRAME, changing the colors again and again, creating a pattern.

The order of the doublets (byte) controlling the COLORS is: Green - Blue - Red.
ff is full brightness - so 0xff0000 is GREEN, 0xx00ff00 is BLUE, 0x0000ff is RED
