Step 3 Building the Controller

The controller is the simplest part of this project. All you need to do is attach your wires to the output pins on your arduino.  Start by connecting wires to pins 2-13.  Then attach a wire to the GND pin on the arduino.  That's it.  I decided to make mine a bit better and soldered it to a prototype shield.  This is optional, but will make the finished product last longer.
