Whether you’re building a robotic arm, an automated door, or a pan-tilt camera system, servo motors are the go-to choice for accurate angular movement. With the help of this guide you can learn how to interface a servo motor with Arduino, make it work, and control its position with the help of provided code.
What is a Servo Motor?
A servo motor is a type of motor used in various applications to precisely control the position, speed, and angular rotation of mechanical systems.
It consists of:
- DC Motor – The main driver
- Gear System – Reduces speed, increases torque
- Control Circuit – Receives signals & adjusts position
- Feedback Mechanism – Ensures accurate movement
Unlike DC motors, servo motors rotate within a fixed range (0° to 180°) and hold their position when powered.
Components Required
For this project, you’ll need:
- Arduino Uno
- SG90 or MG995 Servo Motor
- Jumper Wires
- External Power Source (if using a high-torque servo)
