1) Introduction

When it comes to analog input, it doesn’t get any easier than a basic potentiometer. Nicknamed “pots,” these components are variable resistors. With a twist of their knob you alter the amount of voltage that flows out through their center pin. If you’ve ever adjusted a volume dial chances are, you were using a potentiometer.

Potentiometers can be used for setting a level, determining an angle or just as a simple user interface adjustment. Because you can set them immediately to a value that they’ll hold indefinitely, pots are terrific for prototyping and testing. Use them as a stand-in for any kind of analog input. Let’s get started and add them to your development toolkit!
