Rotary Potentiometer 10kΩ 

Rotary potentiometers are widely used to get input from a user to control light brightness, motor speed, motor position etc. What makes this type of potentiometer so unique is that it does not have a continuous value. This potentiometer has set positions to where you can adjust the potentiometer. It is easy to use these potentiometers with microcontrollers to control output signals.
