int potpin = 57;  // analog pin used to connect the potentiometer
int val;    // variable to read the value from the analog pin

} 
 
void loop()

  val = analogRead(potpin);            // reads the value of the potentiometer (value between 0 and 4095) 
  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
