LED Light Code

C/C++
//Second Photon, LED
int led = D7;



void setup() {

pinMode(led, OUTPUT);
digitalWrite(led, LOW);

Particle.subscribe("invader", myHandler, "43001b001951353337343731");


}

  delay(1000);
  digitalWrite(led, HIGH);
  delay(1000);
  digitalWrite(led, LOW);
  
}

}

PIR Motion Sensor Code

C/C++
// First photon, Motion sensor
int inputPin = D0;              
int ledPin = D1;                
int pirState = LOW;             
int val = 0;                    

int calibrateTime = 10000;      

void setup()
{
  pinMode( ledPin, OUTPUT );
  pinMode(inputPin, INPUT);     
}

void loop()
{

  
  if ( calibrated() )
  {

    readTheSensor();

   
    reportTheData();
  }
}

void readTheSensor() {
  val = digitalRead(inputPin);
}

bool calibrated() {
  return millis() - calibrateTime > 0;
}

void reportTheData() {

  
  if (val == HIGH) {

   
    if (pirState == LOW) {
     
     // Particle.publish("invader", "Detected");
      Particle.publish("invader", "1"); 
      
      pirState = HIGH;
      setLED( pirState );
    }
  } else {
    if (pirState == HIGH) {
     
      pirState = LOW;
      setLED( pirState );
    }
  }
}

void setLED( int state )
{
  digitalWrite( ledPin, state );
}
