Derivation and Notes:

Make sure you have dual wheel potentiometer to reduce

the volume of the audio with your headset. If you don't, 

you might damage your ear drums, your arduino or your headset.

Add a 4.7K ohm resistor from each tone pin to each volume-in

on the potentiometer to further reduce possibility of physical harm.

This arduino sketch is based on the original Sound & Light Machine 

by - Mitch Altman - 19-Mar-07 as featured in Make Magazine 10.

See notes in code below for how I adapted Mitch Altman's version for Arduino

The sleep coding comes partially from here:

***************************************************

2011.02.20

Fixed error in breadboard diagram. 

Added new longer show and gamma frequency (40.4Hz).

2011.02.15

Added liability notice.

2011.02.14

Changed to switch/case format for stage choices.

2011.02.14

Added functions for alternating LED blinking for 

each of the four stages. So now, there are 

eight cases: b, B, a, A, t, T, d, and D.

2011.02.14

I've included a Stereo Eyephone Test sketch 

and a Stereo Tone Test Sketch. These sketches are purely

for development purposes, used to confirm preferred programming

prior to putting it into the Arduino Brain Machine Sketch.

If you're having trouble with Eyephones or Earphones, try

isolating the cause using one of these simpler sketches.
