Introduction: Control a Servo Using an Audio Signal

I was looking for a way to control a servo for school project and i couldn't technically "remote control" it.  I decided to go for the simplest way that i could figure out how to control the servo.  (im sure you could do it much simpler using a digital controller but i didn't have one. )

I learned that you literally tell the servo how far to turn by using what is called pulse width modulation.  I explain how i did the first run in the video using my computer.  I eventually made a recording of my pulses and played the signal from my iphone and that made the servo turn at a certain time.

If anyone is interested i can actually do a write up on the project just let me know.

    PLEASE PLEASE PLEASE PLEASE Do an instructable on this, I am making an animatronic band, and I need audio control for the servos. Would it be possible to do with Arduino?

    What is the name of the software you used? Sounds like you're saying decarda but can't find that in google. Thanks !

    I used a program called dakarta, but any sound generator will do.
