Arduino Sketch

/*
 * This Arduino sketch controls a micro servo motor connected to pin D9.
 * The servo will start at 10 degrees and then move to 130 degrees.
 */

#include <Servo.h>

Servo myServo;  // create servo object to control a servo

void setup() {
  myServo.attach(9);  // attaches the servo on pin 9 to the servo object
  myServo.write(10);  // set initial position to 10 degrees
  delay(1000);        // wait for a second
}

void loop() {
  myServo.write(130); // move servo to 130 degrees
  delay(1000);        // wait for a second
  myServo.write(100);  // move servo back to 10 degrees
  delay(1000);        // wait for a second 
  myServo.write(70);  // move servo back to 10 degrees
  delay(1000);        // wait for a second 
  myServo.write(40);  // move servo back to 10 degrees
  delay(1000);        // wait for a second 
  myServo.write(10);  // move servo back to 10 degrees
  delay(1000);        // wait for a second
  myServo.write(40);  // move servo back to 10 degrees
  delay(1000);        // wait for a second 
  myServo.write(70);  // move servo back to 10 degrees
  delay(1000);        // wait for a second 
  myServo.write(100);  // move servo back to 10 degrees
  delay(1000);        // wait for a second 
  myServo.write(130); // move servo to 130 degrees
}

This code initializes the servo motor and moves it to various positions in a loop. The servo starts at 10 degrees, moves to 130 degrees, and then cycles through several positions before returning to 10 degrees. Each position is held for one second.
