For the hardware I set it up as a prototype on a breadboard then transferred everything to a standalone Arduino configuration. You can do it either directly from a Arduino or get a little more technical with the standalone like I did.
If you choose to go standalone I encourage you to keep a few things in mind:
The pin out of the Arduino and the atMega chip itself is NOT the same. i.e. pin 13 on the chip and Arduino are not the same.
You must have a 5v voltage regulator.
I will assume you are just going to be using the Arduino.
NOTE: If this is your first time using LED's and the Arduino please familiarize yourself with the LED picture I included.
In order to prevent damage to the LED you will need to use a resistor on the Anode side of the LED for this I used a standard 220 ohm resistor.
To clarify you will wire each led from PIN # -> resistor -> Anode then Cathode -> Common Ground
Ensure everything is to a common ground.
Once its all done put each LED into its perspective LED hole in the LED holder without glue.
Wire in a switch or just disconnect your power source.
Secure the lid with the project box screws.
