See below for the code I used:

It is very simple wiring. The output of your servo goes to Pin 9 of the Arduino board.

The other wires of the servo go to power so i powered them directly from the Arduino board, be careful doing this in case your servo draws too much current, you may need an external power supply.

I also wired an LED directly to the 5v power output of the arduino so that I know when it is switched on.

#include <Servo.h>

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

// twelve servo objects can be created on most boards

int pos = 0;    // variable to store the servo position

void setup() {

  myservo.attach(9);  // attaches the servo on pin 9 to the servo object

}

void loop() {delay(1000); //repeat every 10 seconds...

  for (pos = 40; pos <= 140; pos += 1) { // goes from 40 degrees to 140 degrees

    // in steps of 1 degree

    myservo.write(pos);              // tell servo to go to position in variable 'pos'

    delay(20);                       // waits 20ms for the servo to reach the position

  }

  for (pos = 140; pos >= 40; pos -= 1) { // goes from 140 degrees to 40 degrees

    myservo.write(pos);              // tell servo to go to position in variable 'pos'

    delay(20);                       // waits 20ms for the servo to reach the position

  }
