potentiometer based mouse

Archiver

I am working on a somewhat similar problem. I have a potentiometer circuit (0
to 5 volts) that I want to translate into x and y co-ordinates that wil be
used to position a cursor on a computer screen. (ie. potentiometer based
mouse). The pot I am using is "special "and will allow 0 to 340 degrees of
rotation. Any thoughts on how best to translate this 0 to 5 volts (0 to 340
degrees rotation) into X and Y values that could be read by the standard
Mouse drivers on a computer??? Thanks!

If the taper on your pot is linear then the relationship between degrees of
rotation and pot resistance at any degree of rotation is also linear. If it
is not linear then go get a pot with a linear taper.
