Hacking Simon Says: Lego and electrical Simon solver

A project of mine from intermediate school: a Lego Mindstorms machine that plays back the sequence from a Simon Swipe until it beats the game. The Simon has light sensors taped to it, which go through a simple circuit board to connect to the Lego Mindstorms controller. I really wanted mechanical switches (because I thought they were cool), so to repeat the sequence the Lego motors hit switches, sending electrical pulses to the board: activating the buttons in the same way a stylus activates a screen.
