Arduino Basic Tutorial SERVO MOTOR #2

This is a simple example of interfacing some extra hardware to the arduino .

Components required
1)Arduino
2)Servo motor

Servo motor are popular nowadays and these motor comes with different vareities of sizes and strenghts and function and from different vendors. Servos are dc motors with gears on it and is used for precision control of the position of the motor arm.

These have three pins for power , ground and for signal. 

Servos position is defined by the pulse width of the voltage signal in signal pin. 

But we don't have to worry about the pulse here, arduino servo library will do our work . 

We'll look at the code and interfacing on the next part.
