Servo Metal Gear High Torque MG995

Features:

• High torque for precise and accurate movements
• Durable digital metal gears prevent stripping
• Standard size for a variety of applications
• Rotates up to 60 degrees
• Lightweight at 55g
• Comes with arms, screws, and pre-soldered female wires
• Recommended pin usage: pins 9 or 10 (Servo library standard)
• Easy to integrate and control

Principle of Work:

The MG995 servo motor operates using Pulse Width Modulation (PWM). The control wire receives a series of pulses, and the duration of each pulse determines the position of the shaft. A potentiometer measures the shaft's position and feeds back to the control circuit, which adjusts the pulses to maintain the desired angle.

Pinout of the Module:

• GND: Ground connection
• VCC: Power supply (4.8V ~ 6.6V)
• Signal: Control signal input (PWM)

Applications:

• Robotics – precise movement for arms, grippers, etc.
• Automation – positioning in assembly lines, conveyors
• Model making – radio-controlled vehicles
• Medical equipment – positioning systems in devices
• Industrial equipment – packaging, cutting, etc.

Circuit:

Arduino circuit using 5V 4A supply and pin 9 for control:

Library:

No need to install a library; the Servo library is included with the Arduino IDE.

Example Code:

#include <Servo.h>

Servo myservo;

void setup() {
  myservo.attach(9); // attach the servo signal pin to pin 9
}

void loop() {
  for (int i = 0; i < 180; i++) {
    myservo.write(i);
    delay(15);
  }
  for (int i = 180; i > 0; i--) {
    myservo.write(i);
    delay(15);
  }
}
