Control a Servo Using an Audio Signal
Intro: 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?
