About Servo Motor
The MG996R servo motor is a high-torque servo motor capable of lifting up to 15kg in weight. The motor can rotate its handle from 0° to 180°, providing precise control of angular position. For basic information about servo motors, please refer to the Arduino - Servo Motor tutorial.
The MG996R servo motor used in this example includes three pins:
- VCC pin: (typically red) needs to be connected to VCC (4.8V – 7.2V)
- GND pin: (typically black or brown) needs to be connected to GND (0V)
- Signal pin: (typically yellow or orange) receives the PWM control signal from an Arduino's pin.
Since the MG996R is a high-torque servo motor, it draws a lot of power. We should not power this motor via the 5v pin of Arduino. Instead, we need to use the external power supply for the MG996R servo motor.

- Connect Arduino to PC via USB cable
- Open Arduino IDE, select the right board and port
- Copy the above code and open with Arduino IDE
- Click Upload button on Arduino IDE to upload code to Arduino
- See the result: Servo motor rotates slowly from 0 to 180° and then back rotates slowly from 180 back to 0°
