// Include the servo library:
#include <Servo.h>

// Create a new servo object:
Servo myservo;

// Define the servo pin:
#define servoPin 9

//create a variable for speed

const int pot= 0;  //Analog pin to attach potentiometer

// Create a variable to store the servo position:
int angle = 0;

void setup() {
  // Attach the Servo variable to a pin:
  myservo.attach(servoPin);
}

void loop() {
 
  
  int potValue = analogRead (pot);
  potValue = map(potValue, 0, 1023, 10, 100); // reads pot to calculate number for delay.
  // Sweep from 0 to 180 degrees:
  for (angle = 0; angle <= 40; angle += 1) {
    myservo.write(angle);
    delay(potValue);  // new speed for servo.
  }

  // And back from 180 to 0 degrees:
  for (angle = 40; angle >= 0; angle -= 1) {
    myservo.write(angle);
    delay(potValue);
  }
