I have a 1 turn 10k Ohm Potentiometer attached to the analog input of an Arduino. Now, the full range of the pot gives me values from 0 - 1023, nothing new.
The problem: I only want to measure change within a small rotation range of the pot. So the start position is at 30° rotation and the end position is at 40° rotation. I want to achieve a maximal numerical range within those 10°.
Are there any potentiometers that don't turn about 270°? Or can I maybe achieve it by putting more resistance in line?
Appreciate the help! Thank you, Marcel
