Re: Potentiometer on Parallel Port?
The parallel port of your PC has 8 digital signal lines, and a bunch of control lines. It deals with ones and zeros. A potentiometer is an analog device, it deals with varying resistance. So, no you can't just connect a potentiometer to a parallel port. You'd need an analog to digital converter, and then some circuitry and software that would make the converted number show up on the computer in a way you could use it.

I don't know how to do it, but I do know it ain't real easy.
