I think that was the answer I was looking for.Or you can find a servo pot with no stop.
So do i use this instead of the pot. and how many positions to i need. and do you need a microprocessor or a pic for this to work.Gray code rotary encoder.

Digikey has them in a bewildering variety

For the first three, yes.So do i use this instead of the pot. and how many positions to i need. and do you need a microprocessor or a pic for this to work.
thanks
Yes, for the first two options (first three links) described above, you might need a microcontroller. For the last one, maybe, maybe not.Yes to what question.
The circuit is very simple: connect the bottom of the pot to the power supply, bottom to ground. You will get a retiomatric sensor i.e. the ration of the voltage on the wiper to the power supply voltage will be proportional to the angle. Your problem is more mechanical rather than electrical: how are you going to secure the pot to the moving parts?I am looking for a circuit. that when i turn a pot it will tell me how many deg of rotaion i have turned. thanks.
