Purpose
In this lesson, you will learn how to read the values from a Potentiometer and use those values to move a servo.
Understanding potentiometers
A potentiometer is a special type of resistor. By rotating the knob of the potentiometer you can vary the amount of resistance (see image below).
Ground - Ground is the first connection and should be connected to one of the "Analog" pins on the board.
Signal - This should be connected to the "S" or yellow bar pins on the board.
VCC - The is the power pin from the board. As you rotate the potentiometer it restricts or allows for current to flow.
