EL Simón
N.Poole 2011
SparkFun Electronics

I wrote this code just to show off some EL Panel. It originally ran on an EL Sequencer 
Board which had the ARduino Bootloader on it, but feel free to modify it for whatever
hardware you want! The hardware setup is pretty straight-forward: 4 EL Panels are connected
to the A,B,C and D outputs on the Sequencer and 4 Force Sensitive Resistors are mounted 
below them, attached to Analog pins A3-6. Finally, a buzzer or small speaker is connected
between A2 and ground. 

I could have just modified the Simon Game code from our small Simon games but I had always
wanted to write Simon as a programming exercise so this was my quick attempt. I hope you
find it helpful, and enjoy!
