2. Learning Objectives
• Be able to identify characteristics that distinguish a
servo and a DC motor.
• Be able to describe the difference a conventional
servo and a continuous rotation servo.
• Be able to use the Arduino Servo library to control
servo position.

3. What is servo motor?

4. What is servo motor?
• A servomotor is a rotary actuator that allows for precise control of
angular position, velocity and acceleration. It consists of a suitable motor
coupled to a sensor for position feedback. It also requires a relatively
sophisticated controller, often a dedicated module designed specifically
for use with servomotors.
• Servomotors are not a specific class of motor although the
term servomotor is often used to refer to a motor suitable for use in a
closed-loop control system.
• Servomotors are used in applications such as robotics, CNC machinery or
automated manufacturing.

5. DC Motors and Servos:
DC Motor servo
• Motion is continuous. • Capable of holding a position.
• Speed controlled • Speed controlled by delay between
by applied voltage. position updates.
• Hybrid of motor, gears and controller.

6. Conventional and Continuous Rotation

7. How Does the Servo Motor Works?
Pin details:-
1. Black Wire: GND.
2. Red Wire: +5V.
3. Yellow Wire: control signal.

8. Pulse width modulation(pwm)
