In this very simple project you will control a single servo using a potentiometer.
You will need to obtain a standard RC servo; any of the small or mid-sized servos will do. Larger servos are not recommended because they require their own power supply as they consume a lot of current. Also, you'll need a potentiometer; pretty much any value rotary potentiometer will do. I used a 4.7K ohm one for testing. Note that you may also wish to connect your Arduino to an external DC power supply.
