Let us take a look at yet another very useful example of an actuator: the servo motor. A servo motor is a special type of motor that is capable of rotating its shaft at specified angles between 0 to 180 degrees.
A DC powered servo motor has numerous applications in electronic gadgets such as surveillance cameras, DVD players, and basically any application where things need to be moved at particular angles. AC powered servo motors are usually applied in the manufacturing industry to move machinery parts at specified angles - a common example would be a bottling plant:
Internally, a servo motor has a regular DC motor that is integrated with an in-built motor driver circuit. The in-built driver circuit takes care of moving the motor at specified angles. Signals are sent from the Arduino to the servo motor, via an Arduino...
