I'm looking to make a steering angle sensor for my data acquisition system in my race car. I basically need to translate the movement of the steering wheel into voltage read by the logger unit.
The logger provides a 5v reference signal so I figured I could send that signal through a potentiometer then back to the unit.
most commerical units available ($$$) use a system of pulleys driven off of the movement of the steering shaft itself.
some questions -
what type of pot would be good for this application. I understand audio ones are not linear enough?
Anyone have any idea where I can get different sized pulleys to go on the end of the pot?
any other tips advice or different ways of doing it?
thanks!
