Arduino streaming player to AY-3-8910 / YM-2149

Here's a better sounding video of what my project sounds like. It streams a YM file from my computer, sends it through the USB port (which acts as a serial device) into the Arduino. Then the Arduino decodes the bytes from the serial port and then sets the necessary pins on the AY-3-8910. I had a lot of fun working on this project and was very happy when it worked.
