int potPin = 0;   // select the input pin for the potentiometer

int motorPin = 12; // select the pin for the Motor

int ledPin = 7;

int val = 0;      // variable to store the value coming from the sensor

void setup() {

  Serial.begin(9600);

}

void loop() {

  val = analogRead(potPin);    // read the value from the sensor, between 0 - 1024

  Serial.println(val);

  analogWrite(motorPin, val/4); // analogWrite can be between 0-255

  analogWrite(ledPin, val/4);

}
