int potValue = 0;   // value read from the pot

}

void loop() {

  potValue = analogRead(potPin); // read the pot value

  analogWrite(led, potValue/4);  // PWM the LED with the pot value (divided by 4 to fit in a byte)

  Serial.println(potValue);      // print the pot value back to the debugger pane

  delay(10);                     // wait 10 milliseconds before the next loop
