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!
The sound you're hearing is coming entirely from the motors. The song information is taken from a MIDI file that I composed. An Arduino provides the necessary commands to spin the motors at the required frequencies.
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.
Answers to common questions:
Q: Hey that's awesome! Will you send me the G code?
A: There is no G code. This is an arduino.
Q: Oh... will you teach me exactly how to do it?
Q: Where are the other videos?
A: I'm doing other things. I've got grand plans to improve this project but it's nowhere near the top of my priority list these days.
Q: What hardware did you use?
A: The stepper motors are bipolar NEMA 17 motors. The microcontroller is the Arduino Deumilanove. The power supply is 24 V, 4 amp. I am also using a 3-axis stepper motor driver board manufactured by Xylotex (xylotex.com). I actually don't recommend the Xylotex board anymore. Instead, try the drivers available at Probotix.com.
