// C++ code

void setup() {

  // initialize serial communication at 9600 bits per second:

  Serial.begin(9600);

   pinMode(IR, OUTPUT);

  pinMode(Alarm, OUTPUT);

// the loop routine runs over and over again forever:

void loop() {

  // read the input on analog pin 0:

  int sensorValue = analogRead(A0);

  // print out the value you read:

  Serial.println(sensorValue);

  delay(1);  // delay in between reads for stability

if(sensorValue > 100 )

{

Serial.print("yes now on ");

 digitalWrite(Alarm, HIGH);
