Hello,
I have a requirement to control a motor with a an audio signal. More specifically a sine wave around 20hz.
The rotational offset of the motor must match the rotational position indicated by the sine wave stay phase locked to it. If the sinewave has a glitch, then the motor must readjust as quickly as possible.
The motor will be used to drive a piston , and be as quiet as possible.
The motor should have enough power to push a mass of about that of a tennis ball back and forth at 20hz.
Can anybody suggest the simplest way of doing this? I'm happy to use an ardunio if required, but though there may be a cheaper way.
many thanks indeed.
Gavin
