Step 2: assemble the board(the LED cube base)
(Detour available skip to next step)
In this step you will need the board and the wiring. First you will want to map out were all the wires will go and then feed the wires through the board. Don't mind the LED and resistor note on the picture for now.
NOTE: I recommend you use Different color wire just because you won't get confused which wire is which.
