We will concern ourselves with a standard servo motor for this article. Instead of using the PWM signals for controlling the angle of motion, it uses them to control speed and torque. Continuous motion servo motor: This servo motor rotates continuously.Hence it finds applications in projects like robotic arms, wing flap control of an airplane, etc. Standard/Limited motion servo motor: This servo motor usually rotates up to a maximum of 180 degrees.

How to select a suitable Servo Motor for an Arduino project? If the pulse sent is different from the previous one, the motor will change position accordingly. So if you wish to hold the position, send the same pulse 20ms apart. The refresh rate of the servo is about 20ms. A maximum pulse of about 2ms turns the servo to 180 degrees. A neutral position is the one from where it can potentially turn equal distances in either direction. A neutral pulse (around 1.5ms) is required to get the shaft in a neutral position. There are three types of pulses that a servo recognizes.Ī minimum pulse is a pulse needed for the servo to stay at 0 degrees of rotation. The control is done by giving a pulse of a particular duration to the control wire. We have a complete guide on how to use PWM with an Arduino Uno. You need to use pulse width modulation to control the angle of rotation. How to control the angle of a servo motor? Conversely, it will run at minimum speed when the shaft needs to turn a small distance. Proportional control: The motor will run at maximum speed when the shaft needs to turn a considerable distance. The distance to be traveled is proportional to the applied power. Quite unlike the DC motors that run in complete loops as long as power is supplied to it. This motor allows you to rotate to a certain degree. Whenever you have a requirement where you need to control the angle of rotation of the axis of a motor, you can use the servo motor. Or, more commonly, in robotic applications. The servo motor is usually needed for electromechanical projects. Why should we interface the servo motor with Arduino? What are the components required for servo motor interfacing with Arduino?
