Hi I am making a bike handle with a Potentiometer attached to it so that the Potentiometer will rotate with the handle and the Potentiometer will be able to tell me what direction the handlebar is rotated.
The potentiometer will be powered by the USB of a computer or a battery (5 - 9 V, undecided yet)
I went to Digikey to buy them, but there are so many parameters to choose from, I have not idea what to look for.
Rotary - Linear | Digi-Key
Here are a couple parameters that I need help with: Resistance, Rotation, Number of Turns and Temperature Coefficient.
For example, in my application where my goal is to be able to read accurately the value of the pot so I know which direction and what angle the handlebar is, which resistance should I choose?

my theory for resistance value is that the higher the resistance of the pot, the more variation I will get for my output voltage when I turn the pot, this will make my readings more accurate.
