Wiring The Circuit





First, snap the pin header in to 3 pieces that fit the Arduino Unos digital and analog plug-ins. Strip and start soldering wires to the 16 digital leads(columns) on the perf board. For the 4 analog leads(layers), solder 100 OHM resisters to the leads then solder wires to each resisters lead. Next strip and solder the opposite ends of the wires to the 3 pin headers. The wiring is setup to resemble a graph with a 3rd dimension. For the columns, there are two axes X and Y. In addition, the layers serve as the Z axis. If you look straight down from the top of the LED cube it looks like the 1st quadrant on a graph except that the origin is (1,1) on the cube. Likewise each LED can be named using the fundamental graphing technique. Lets try an example; look at the demonstrational picture and find A(1,4). "A" means that it is on the first layer and "(1,4)" is X=1,Y=4 on the graph.
