  19. Create an array of values to control each LED NODE in the standard RadioShack strip.
  20.  
  21. PROGMEM will assign values to store in the AVR chip's RAM memory as a two dimensional array.
  22.  
  23. We will then read out these values to create a serial pulse train OUTPUT to the LED Strip.
  24.  
  25. Each ROW is sent as OUTPUT and will SET the COLOR for each of the TEN (10) nodes .  
  26.  
  27. Each ROW is a NEW FRAME, changing the colors again and again, creating a pattern.
  28.  
  29. The order of the doublets (byte) controlling the COLORS is: Green - Blue - Red.
  30. ff is full brightness - so 0xff0000 is GREEN, 0xx00ff00 is BLUE, 0x0000ff is RED
