Please see our Potentiometers lesson as part of our Intro to Input series.

Are Potentiometers even sensors? Well, they are a type of variable resistor and often used to sense human input, so I would say yes! :)

A video demonstration of a trimpot hooked up to analog input A0 on the Arduino and its value graphed on an OLED display in real-time. The code is available here.
