Something like this might work: http://www.amazon.com/Cable-Converter-Music-Keyboard-Window/dp/B0017H4EBG You can also use the USB on the Arduino as a regular serial port, and run a program on your PC that converts it to MIDI, but that usually ends up being a pain. Good luck!! It’s possible to do with an Arduino UNO or Mega 2560:

First , congrats for the project! Im starting to build one from an old broken organ, and would like to know if it'd be possible to serial out from arduino into a pc usb virtual midi using arduino uno's usb interface instead of real midi out interface on pin 13. My intention is to hook up the organ into my pc via usb (pc has no midi interface), and then i'll control virtual instruments via organ keys. Hi there! First , congrats for the project!

Many thanks for posting this. line 41 of realtimechart.py

data = (data – 130.0 – voltoffset/voltscale*25) / 25 * voltscale + voltoffset

I also had to
plot.plot(t1[0:600], d1[0:600])
plot.plot(t2[0:600], d2[0:600])

Which gives me a slightly bogus plot.

Many thanks for posting this.

I've actually been searching for a project like this on my journey towards becoming an electronic enthusiast like you :D . Thanks so much for this post. I just placed an order for my own arduino microcontroller and would like this project to be my first.Can you pleeeeeaasssee send me the schematics or pictures of how you rigged the the microcontroller and the servo together...,please ...:( Hey Mahto,

Thanks for publishing your code. I used your first class to work with a Tektronix 2024C scope with no problems. It only took me a few hours searching to find you :-) Great work! Hey this was great.
