Servos are composed of an electric motor mechanically linked to a potentiometer and they are able to translate the width of the pulse into a position. When you command the servo  to rotate, the motor is powered until the potentiometer reaches the value corresponding to the commanded position.

Today we’d like to share with you a tutorial with the aim of showing how to make a simple light follower made of cardboard using Arduino Uno and a microservo, in this case the Analog 180° Micro Servo.

Follow the step by step lesson to build one yourself.
