The first thing we need to do is get all of our supplies.
We're going to need...:
*125 LEDs (make sure they are red or yellow or the arduino will not be able to run it)
*wire, lots of wire
*5 3-8 line decoders
*5 NPN Transistors
*30 150 Ohm resistors
*a bread board ( preferably 3x 5 inches)
* soldering iron (always wear your safety glasses)
*sponge (for cleaning the soldering iron)
*conductive rods ( you can get 3/64 brass rods in a 6 pack at hobby lobby for about three dollars; get about 6 or7)
* wire cutters
*needle nose pliers
Step 1: Step 1 cutting the rods
First take your rods and get them all the right length. cutting two inches off every rod then cutting the rest in half to five inch pieces.
once you have all of them cut we can move on to the next step.
Step 2: Step 2 make the frame
Next we need to take three rods for each layer and make the ribs.
take a ruler and a permanent marker to measure out 1 inch increments on two opposite sides of each square. these points are going to be where you solder the ribs to the square, again make sure that they are at a 90 degree angle. you'll also want to measure out one inch increments on each rib, you'll thank me later.
when you're done you should have five squares with three lines running through them.
it should look like this
