Introducing the Potentiometer
A potentiometer is a resistance-based analog sensor that changes its
internal resistance based on the rotation of its knob. The potentiometer has
an internal voltage divider enabling you to read the change in voltage on
the center pin with a microcontroller (the RedBoard). To hook up the
potentiometer, attach the two outside pins to a supply voltage (5V in this
circuit) and ground. It doesn’t matter which is connected where, as long as
