  {

  Serial.begin(9600);

  val = 0;

  pinMode(13, OUTPUT);

  }

  void loop()

  {

  val = analogRead(A0);

  if (val > 200) {

  digitalWrite(13,HIGH);

  } else {

  digitalWrite(13,LOW);

  }

  Serial.print(“Current value is : “);

  Serial.print(val);

  Serial.println(” “);

  delay(100);
