Servo Motor Control

Z2M Parts: MMD-00002-A, MMD-00002-B

Control a servo motor to rotate to specific angles using PWM signals.

Circuit Diagram

Wire Connections & Pin Configuration

Wire Color Connections:

Orange/Yellow → Digital Pin 9 to Servo signal
Red → 5V to Servo power
Black/Brown → GND to Servo ground

Pin Configuration:

Arduino Digital Pin 9 → Servo signal (orange/yellow)
Arduino 5V → Servo power (red)
Arduino GND → Servo ground (brown/black)

Arduino Code

Edit

#include <Servo.h>

Servo myservo;
int ang;

void setup() {
  myservo.attach(9);
}

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

Instruction Details

Wiring: Connect servo signal wire (orange/yellow) to Digital Pin 9, power (red) to 5V, ground (brown/black) to GND. For high-torque servos, use external 5–6V supply.
Library: Not required (built-in Servo library).
Upload Code: Tools → Board → Arduino Uno. Tools → Port → select your COM port. Click Upload button.
View Output: Servo motor will sweep from 0° to 180° and back continuously.
