Is used to read the last angular value written to a servo variable. writeMicroseconds(1500) will rotate the servo motor shaft to 90° position. Most servo motors with 0°-180° angles of rotation are mapped to 1000 – 200 microseconds.Į.g. We have talked about it in the previous tutorial tutorial on How servo mottor works. This is actually the basic way of operating a servo motor. WriteMicroseconds(): this function is used to send PWM signal in microseconds to the servo motor to move it. This code will rotate the servo motor shaft to 90° position. The servo motor is the desired angle from 0° to 180°. my_servo.attach(12), where my_servo is the servo variable name, 12 is the arduino pin on which the servo is attached.įunction used to write information to the servo motor. List of Arduino Functions to Use a Servo MotorĪttach() write() writeMicroseconds read() attached() detach()Īttach(): this function is used to attach the servo signal pin to an arduino pin. Used to operate and control a servo motor. To operate the servo motor we will first list out the various arduino functions Code to operate a servo motor is very simple, however, before we write the code
