EQUIPMENTS/SOFTWARE:
• Arduino Uno/Mega
• Potentiometer
• Servo motor
• Connection wire
• Arduino IDE
• Proteus
PRE-LAB THEORY/INTRODUCTION:
SERVO MOTOR: A DC motor along with servomechanism (closed-loop control system) acts
as a servo motor which is basically used as a mechanical transducer in the automation industry.
Based on its accurate closed-loop control, it has versatile applications used in many industries.
The DC servo motor definition is, a motor that is used in servo systems is known as a servo
motor. A servo system is a closed-loop system where the feedback signal (position, velocity,
acceleration, etc.) drives the motor. This signal acts as an error and based on controller, accurate
position or velocity is achieved. The motors are coupled to an output shaft (load) through a
gear train for power matching. Servo motor acts as a mechanical transducer as they convert an
electrical signal to an angular velocity or position.
WORKING PRINCIPLE: Servo motor works on the PWM (Pulse Width Modulation)
principle, which means its angle of rotation is controlled by the duration of pulse applied to its
control PIN. Basically, servo motor is made up of DC motor which is controlled by a variable
resistor (potentiometer) and some gears.
