Potentiometers are very powerful components that allow a variety of cool capabilities when incorporated into a project. A potentiometer is a knob, which can be used to control all manner of different components in your project. The potentiometer is basically a variable resistor, whose resistance depends on the position of the knob. We can use a potentiometer to do things like control the volume in a speaker, or to control the brightness of an LED. If you want to follow along at home, you can order the Arduino Kit we are using HERE.
