In this section, you learn interfacing of servo motor with Arduino, but before this let’s start with servo motor.
A servo motor is an electrical device used to rotate objects at certain specified angles. It’s just a basic motor that runs through the mechanism of the servo.
They are used in numerous applications such as toy cars, robotics, machines etc.
Servo motors are measured in kg / cm (kilogram per centimeter). Servo motors are rated 3kg / cm or 6kg / cm etc. This kg / cm tell you how much weight your servo engine can lift at a given distance. Generally servo motor 9G SG90 is used in projects.
