Step 4The LED/Breakout board
This part is slightly harder, but still simple. You now need to make up the LED array. Start by placing all of your leds on the breadboard. Connect all of their grounds together. Now attach the wires that you connected to your arduino. Finally, connect a resistor between your ground on the breadboard to the ground on the arduino.
I recommend that you wrap your electronics in plastic to prevent them from getting all gooey.
The schematic below should help.
