Tutorial: How to Use RDS3120MG 20KG 180 Degree Servo

The RDS3120MG servo is ideal for projects requiring precise movement and position control, such as robotics, mechanical prototypes, and modeling. This servo is suitable for both beginners and experts seeking a reliable and powerful servomechanism.

What you need

• Arduino Uno
• USB Connection
• 5V Power Supply
• Servo Connections

Steps

1. Connect the servo to the Arduino control pin (check the datasheet for the specific pin)
2. Connect the servo mass (GND) to the 5V power supply
3. Connect the servo VCC pin to the 5V power supply
4. Open the Arduino IDE and load the example sketch
5. Check the servo rotation between 0° and 180°
6. Adjust the code to customize the range of motion
7. Test the servo’s reactivity with varying inputs
8. Check the stability of the servo during rotation

Example code

void setup() {
  pinMode(9, OUTPUT); 
}

void loop() {
  for(int pos = 0; pos <= 180; pos += 1) {
    myservo.write(pos);
    delay(15);
  }
  for(int pos = 180; pos >= 0; pos -= 1) {
    myservo.write(pos);
    delay(15);
  }
}

Mini project

Build a basic signaling system with the RDS3120MG servo. Use a motion detector to rotate the servo when motion is detected.

Common mistakes

• Do not verify the correct power supply voltage
• Do not connect the pins correctly
• Do not check the servo rotation before uploading the sketch
• Do not adjust the code to fit your project

Recommended accessories

• Servo connections
• 5V power supply
• Motion detector
• Arduino Uno

Frequently asked questions
