Project by Recyclerobot from Instructables dot com.
The classic memory game Simon has been recreated in many forms using the Arduino development platform, with an almost infinite amount of variations with regards to the controls and outputs. However Instructables member recyclerobot has taken things further and not only shows how to make the game with a solderless breadboard, but also transfer it to a custom PCB.

This example project has been created with Autodesk 123D Circuits – an interesting online simulator and circuit design centre which is worth exploring as well.
