Utilized Tone() for BEEGEES Melody
I utilized the built-in Arduino Tone() function and "pitches.h" header to recreate the BeeGees melody. It looks a lot cleaner in the code, and it's easier to figure out the melody (which is also now in a nice looking array). The only down side is that the volume is about half. I would love to hack the arduino Tone() function to be able to play the tone on both sides of the buzzer. But for now, I think the cleaner code is more important.
