// Arduino Servo Motor Sweep Example
// Servo connections:
//   Signal → Digital Pin 9
//   VCC    → 5V
//   GND    → GND

#include       // Include the Servo library

Servo myServo;          // Create a Servo object

void setup() {
  myServo.attach(9);    // Attach the servo to digital pin 9
}

void loop() {
  // Sweep from 0° to 180° in 10° increments
  for (int angle = 0; angle <= 180; angle += 10) {
    myServo.write(angle);   // Set the servo position
    delay(200);             // Wait for the servo to move
  }

  // Sweep back from 180° to 0° in 10° decrements
  for (int angle = 180; angle >= 0; angle -= 10) {
    myServo.write(angle);   // Set the servo position
    delay(200);             // Wait for the servo to move
  }
