  22. Create an array of values to control each LED NODE in the standard RadioShack strip.
  23.  
  24. PROGMEM will assign values to store in the AVR chip's RAM memory as a two dimensional array.
  25.  
  26. We will then read out these values to create a serial pulse train OUTPUT to the LED Strip.
  27.  
  28. Each ROW is sent as OUTPUT and will SET the COLOR for each of the TEN (10) nodes .  
  29.  
  30. Each ROW is a NEW FRAME, changing the colors again and again, creating a pattern.
  31.  
  32. The order of the doublets (byte) controlling the COLORS is: Green - Blue - Red.
  33. ff is full brightness - so 0xff0000 is GREEN, 0xx00ff00 is BLUE, 0x0000ff is RED
