Remote Amplifier Control

So I have been playing with my Arduino Uno
Ive manged to get blinking LED's, Dimmer Switches and more working.
But today i finally had a go at servos - with nice results!
The code is not written by me & it is included within the Arduino Software.
Code :

// Controlling a servo position using a potentiometer (variable resistor)
// by Michal Rinott <http://people.interaction-ivrea.it/m.rinott>

#include <Servo.h>

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

int potpin = 0; // analog pin used to connect the potentiometer
int val; // variable to read the value from the analog pin

void setup()
{
  myservo.attach(9); // attaches the servo on pin 9 to the servo object
}

void loop()
{
  val = analogRead(potpin); // reads the value of the potentiometer (value between 0 and 1023)
  val = map(val, 0, 1023, 0, 179); // scale it to use it with the servo (value between 0 and 180)
  myservo.write(val); // sets the servo position according to the scaled value
  delay(15); // waits for the servo to get there
}
