Code

Photon 1

C/C++
This code takes the input from the buttons (used as sensors to see when the doors are opened or closed) and uploads it to the cloud for the other photon to download and then graph.
// We will be using D1 to control our LED
int ledPin = D1;
int led = D7;
int lasttime = 0;

// Our button wired to D0
int buttonPin = D0;


void setup()
{


  pinMode( buttonPin , INPUT_PULLUP); // sets pin as input

 pinMode( led , OUTPUT ); 
  pinMode( ledPin , OUTPUT ); // sets pin as output
  Particle.subscribe("Task_Complete", anything, "200022001247343438323536");
}

void loop()
{
   // find out if the button is pushed
   // or not by reading from it.
   int buttonState = digitalRead( buttonPin );


  if(buttonState==1)
  {
    // turn the LED On
    digitalWrite( ledPin, HIGH);
  }
  else{
    // otherwise
    // turn the LED Off
    digitalWrite( ledPin, LOW);
    
  }    



    if ((lasttime == 0) && (buttonState == 1))
  {

        // Send a publish...
        int success = Particle.publish("Door_Status","1",PRIVATE);
        delay(2000);
        

      }else{
          // Otherwise, this isn't a new status, and we don't have to do anything.
          
         
      }
       if ((lasttime == 1) && (buttonState == 0))
  {

        // Send a publish...
        Particle.publish("Door_Status","0",PRIVATE);
        delay(2000);
        

      }else{
          // Otherwise, this isn't a new status, and we don't have to do anything.
          
         
      }
      lasttime = buttonState;
}
      
void anything(const char *event, const char *data)
{
    digitalWrite(led, HIGH);
    delay(1000);
    digitalWrite(led, LOW);
    delay(1000);
}
  

Photon 2

C/C++
This code pulls the data from the cloud and then blinks the on-board LED in pin D7 and graphs sensor data using the Blynk application.
int led = D7;
int lasttime = 0;
void setup() {


 pinMode(led, OUTPUT);
 digitalWrite(led, 0);
 Particle.subscribe("Door_Status", myHandler, "270034001247343438323536");

}
void loop() {
     int buttonstate = digitalRead(led);
     
     if ((buttonstate==1) && (lasttime == 0)){
         //Particle.publish("Task_Complete","Done", PRIVATE);
     }

    digitalWrite(led, 0);
    lasttime = buttonstate;
 }
 
void myHandler(const char *event, const char *data)
{
    digitalWrite(led, 1);
    delay(1000);
    //delay(1000);
    

    
}
