Simply speaking the control electronics adjust shaft position by controlling DC motor. The RED wire is connected to power, Black wire is connected to ground and YELLOW wire is connected to signal.Ī servo motor is a combination of DC motor, position control system, gears. The position of the shaft of the DC motor is adjusted by the control electronics in the servo, based on the duty ratio of the PWM signal the SIGNAL pin. A servo motor will have mainly there wires, one is for positive voltage another is for ground and last one is for position setting. Servo motors are available at different shapes and sizes. So you have to use separate power supply for the motors, either it be from some adapters (5v 2A) or from good quality 9v batteries.īefore going into detail, first we should know about Servo Motors. Connecting multiple Servo Motors with Arduino seems to be easy and but if we connect all the Servos to Arduino supply pins then they won’t work correctly because of lack of enough current to drive all the motors.

Here, we are going to show you that how to control Multiple Servo Motors with Arduino. In the figure given below two servo motors are connected to 1 Arduino.Using one or two Servo with Arduino is Easy but what if we want to use more than one Servo Motors? } C) Driving Two Servo Motors in a loop using Arduino Servo Library: #include } B) Driving Servo Motor in a loop using Arduino Servo Library: #include

A) Driving Servo Motor to a particular degree position using Arduino Servo Library: #include So now lets try to run the servo motor using this servo motor library. And by using the servo motor library its very easy to run more than 1 servo motor using Arduino. Using this library you can easily define the degree to which you want your servo motor to rotate to.

Now there’s a more convenient way of running servo motor which is by using Servo Motor Library. } How to Drive Servo Motor using Servo Library?

PWM pin Code to run Servo Motor using Arduino: #define servo 9 Servo Motor can be run using Arduin by using simple digital write commands that generates Pulses on the selected digital i/o pin and here’s the code for the same: Note: Please keep in mind that the voltage required to run servo must be between 4 to 6 volts Read Also: Beginners Guide to Ultrasonic Sensors before this Arduino Servo Motor Guide. Pulse width for respective degree position Whereas with a servo motor you can precisely control the rotation or movement of the shaft according to your requirements. Then on operating the dc motor, you will observe some delay during starting and stopping of the motor.ĭue to this, it’s difficult for you to figure out when to power it on and when to power it off. Suppose you want to make a project where precise motor control is needed. NOTE: You can also watch this “Servo Motor Step by Step Guide” video for better understanding or read the written tutorial below: Servo motor is composed of 4 important parts: A dc motor, Some Gears, a Potentiometer(position sensor), and a Control circuit.Īnd this whole assembly gives us the precise control or rotation of the shaft of the motor. By the end of this post, you will have a clear understanding of servo motors, how they work and how to use a Servo Motor with Arduino. Servo Motor is one of the most widely used motors in toys, CNC machines, 3D printers for precise control.
