Code

Motion Sensor Circuit

C/C++
This is the code that is connected to the PIR sensor and will communicate to another particle if there is motion detected.
  /*
     * Christmas Lights
     */
     
    int ledPin = D7;                // pin for the LED
    int inputPin = D0;               //  input pin (for PIR sensor)
    int pirState = LOW;             // assuming no motion detected
    int val = 0;                    // variable for reading the pin status
    void setup() {
      pinMode(ledPin, OUTPUT);      // declare LED as output
      pinMode(inputPin, INPUT);     // declare sensor as input
      Particle.subscribe("Joseph_christmas_lights", myHandler);
      Serial.begin(9600);
    }
 void loop(){
      val = digitalRead(inputPin);  // read input value
      if (val == HIGH) {            // check if the input is HIGH
        digitalWrite(ledPin, HIGH);  // turn LED ON
        if (pirState == LOW) {
          // turned on
          Serial.println("Motion detected!");
          Particle.publish("Stephen_christmas_lights","intact");
          //  print on the output change, not state
          pirState = HIGH;delay(600000);
        }
      } else {
        digitalWrite(ledPin, LOW); // turn LED OFF
        if (pirState == HIGH){
          // turned off
          Serial.println("Motion ended!");
          Particle.publish("Stephen_christmas_lights","broken");
          // We only want to print on the output change, not state
          pirState = LOW;
        }
      }
    }
    
    void myHandler(const char *event, const char *data)
{

  if (strcmp(data,"intact")==0) {
    // if your buddy's beam is intact, then turn your board LED on
    digitalWrite(ledPin,HIGH);
  }
  else if (strcmp(data,"broken")==0) {
    // if your buddy's beam is broken, turn your board LED off
    digitalWrite(ledPin,LOW);
  }
  else {
    // if the data is something else, don't do anything.
  }
}

Relay Circuit

C/C++
This is the code that the other Particle Photon uses. It is just connected to a relay switch.
  /*
     * Christmas Lights
     */
     
    int ledPin = D7;                // pin for the LED
    int inputPin = D0;               //  input pin (for PIR sensor)
    int pirState = LOW;             // assuming no motion detected
    int val = 0;                    // variable for reading the pin status
    void setup() {
      pinMode(ledPin, OUTPUT);      // declare LED as output
      pinMode(inputPin, INPUT);     // declare sensor as input
      Particle.subscribe("Stephen_christmas_lights", myHandler);
      Serial.begin(9600);
    }

    void myHandler(const char *event, const char *data)
{

  if (strcmp(data,"intact")==0) {
    // if your buddy's beam is intact, then turn your board LED on
    digitalWrite(ledPin,HIGH);
  }
  else if (strcmp(data,"broken")==0) {
    // if your buddy's beam is broken, turn your board LED off
    digitalWrite(ledPin,LOW);
  }
  else {
    // if the data is something else, don't do anything.
  }
}
