DC motor connected to a potentiometer

Also, connected the 10K potentiomenter to a LED.

Here is the result!

  void setup()

{

  pinMode(in1Pin, OUTPUT);

  pinMode(in2Pin, OUTPUT);

  pinMode(enablePin, OUTPUT);

  pinMode(switchPin, INPUT_PULLUP);

  pinMode (led, OUTPUT);

  pinMode (Movementsensor,INPUT);

}

void loop(){

     if(digitalRead(Movementsensor) == HIGH){

                int speed = analogRead(potPin) /4;

      boolean reverse = digitalRead(switchPin);

      digitalWrite (led, HIGH);

      delay(255-speed);

      digitalWrite(led,LOW);

      delay(255 - speed);

      setMotor(speed,reverse);

     }

     if(digitalRead(Movementsensor+º) == LOW){       

        int speed = 0;

      boolean reverse = digitalRead(switchPin);

      digitalWrite (led, LOW);

      delay(255-speed);

      digitalWrite(led,LOW);

      delay(255 - speed);

      setMotor(0, reverse);

               }

                  }

     void setMotor(int speed, boolean reverse)

{

  analogWrite(enablePin, speed);

  digitalWrite(in1Pin, ! reverse);
