ARDUINO SERVO MOTOR HOW TO

The servo will turn left or right according to the width of this pulse. If you aren't familiar with it, a pulse is simply a square waveform that goes from 0V to another voltage for a set period of time, before returning to 0V. In order to control the rotation, we send a pulse of a variable width on the signal wire (the power and ground wires used as references for the signal). Servo motors tend to work from the 0-6V range, especially the hobby servos we are used to seeing in the Makersphere.

Linear Servo – Allows you to have linear motion with servo motor control.

Continuous Rotation Servos- These servos allow you to continually turn either clockwise or counter-clockwise indefinitely.

Great for robotic arms, pulling/pushing levers etc.

Fixed Rotation Servos – These servos have fixed limitations in their rotation, so you can’t turn it past its limitations.

There are a couple of types of servo you can get: This resistance is known as the Torque Rating of the servo and will be found on the datasheet. Once the motor reaches the position specified by the signal, it will hold its position and resist any forces that try to move it from that position. This position is dictated by what is sent on the signal wire. We'll be controlling our servo using PWM on an Arduino.Ī servo motor is a little different, using 3 connections (Power, Ground, and Signal) to move the motor to a certain rotary position.

Servo motors are extremely useful in so many different applications it’d be good to learn how to control them! Solenoid and DC motor control have been shown already for the most part, they are both pretty straightforward (only power and ground connections) methods of motor control.
