Now that I’ve figured out how to store song information in flash memory on the Arduino, I can actually play full songs. This is a little suite of Mario Brothers themes that I put together. Enjoy!

Motor #2 buzzed a bit on the table this time. I’m going to find a better way to hold the motors still while still allowing them to vibrate.
