### Logical setup. 
Once connected the boards are divided into 6 x 6 squares with a 1 row border around the edge and a one row border between each square. 
The LED boards are wired in a snaking fasion, so in order to light up a 4x4 square, the code has to do some inversion of positioning for every other row (if the starting row started 5 positions from the begining of that row, then the next row will need to start 9 (5+4) positions from the end of the next row).

Drill 3 holes larger (1/2 in) a row up and a row down from center so that the LED Board wires can be threaded.
