  7. #include <Servo.h>

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

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

  14. void setup() {
  15.   myservo.attach(9);  // attaches the servo on pin 9 to the servo object
  16. }

  18. void loop() {
  19.   val = analogRead(potpin);            // reads the value of the potentiometer (value between 0 and 1023)
  20.   val = map(val, 0, 1023, 0, 180);     // scale it to use it with the servo (value between 0 and 180)
  21.   myservo.write(val);                  // sets the servo position according to the scaled value
  22.   delay(15);                           // waits for the servo to get there
  23. }
