![]() Good places to buy them are Servocity, Sparkfun, and Hobbyking. Hitec and Futaba are the leading RC servo manufacturers. There are few big names in the servo motor world. An Arduino board connected to a computer via USB.The first motor I ever connected to an Arduino, seven years ago, was a Servo motor. Here we will see how to connect a servo motor and then how to turn it to different positions. With time, they found their uses in robotics, automation, and of course, the Arduino world. Servo motors were first used in the Remote Control (RC) world, usually to control the steering of RC cars or the flaps on a RC plane. ![]() Using the Arduino, we can tell a servo to go to a specified position and it will go there. Usually, they have a servo arm that can turn 180 degrees. It also attaches the MG995_Servo instance to pin 6.Servo motors are great devices that can turn to a specified position. Void setup: The void setup section initializes the Serial communication with the standard baud rate of 9600 bps. * This example Arduino Sketch controls the complete rotation of Furthermore, create an instance MG995_Servo of the servo library functions. We have connected the signal pin of the motor to the PWM pin 6 of Arduino. Then restart the Arduino IDE software and include it into the sketch. Library Installation & Pin Declaration: For easy interfacing, install the servo motor library i.e “Servo.h”. Serial.println("0") //Turn left high speed MG995_Servo.attach(Servo_PWM) //Always use attach function after detach to re-connect your servo with the board You can use deatch function or use write(x), as x is the middle of 0-180 which is 90, but some lack of precision may change this value MG995_Servo.write(0) //Turn clockwise at high speed Serial.println("0") // You can display on the serial the signal value MG995_Servo.attach(Servo_PWM) // Connect D6 of Arduino with PWM signal pin of servo motor Serial.begin(9600) // Initialize UART with 9600 Baud rate Servo MG995_Servo // Define an instance of of Servo with the name of "MG995_Servo" #define Servo_PWM 6 // A descriptive name for D6 pin of Arduino to provide PWM signal #include // include servo library to use its related functions * SG995 Servo motor by using its PWM and Pulse width modulation technique Here is a small example code to brief the use of this motor practically. The wiring diagram to show the connections is provided below: Connect the PWM input pin of the motor to the Arduino PWM output pin D6 to control and rotate the motor.Connect the power voltage pins of the MG995 Servo motor to the 5 Volts pin and the GND pin of the Arduino UNO.Moreover, almost all Arduino board provides PWM signal. We will use Arduino uno in this tutorial, but you can use any Arduino board which provides at least one PWM signal output. In this section, we will learn to interface SG995 servo motor with Arduino. Interfacing MG995 Servo Motor to Arduino UNO To keep things convenient, specific libraries are written to control and interface the motor instead of setting the PWM values every single time. In this way, we can measure and control our motor to desired degrees. Similarly, a 2.5ms ON-time signal leads to 180-degree axial position. To rotate the motor axis to 90 degrees, the signal should be high for 1.5ms. If the PWM signal is high for 0.5ms in a single cycle, the axis moves to zero degrees. There are some standard calculations for degree rotation. The position of the axis of the motor depends on the duty cycle of the signal. That is why each cycle of the PWM signal is of 20 milliseconds. Any value more or less leads to malfunctioning of the device. The concerned Servo motor can operate only at 50 MHz of frequency. The working principle of this motor is pulse width modulation. The MG995 Servo motor has a signal input pin to rotate the motor. The motor is energized using the power pins that are VCC and GND.
