Doorbell Photon

C/C++

int in = A1;
int light = D7;

void setup() {
pinMode(light, OUTPUT);
digitalWrite(light, LOW);
pinMode(out, OUTPUT);
digitalWrite(out, HIGH);
pinMode(in, INPUT);
Particle.subscribe("Jared", Ring);
}

void loop() {
   int switchstate = digitalRead(in);
   if (switchstate == HIGH) {
       Particle.publish("Spencer", "DING DONG");
       delay(1000);
   }
   else if (switchstate==LOW) {
       Particle.publish("Spencer", "SILENCE");
       delay(1000);
   }
}

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

if (strcmp(data, "HELLO")==0) {
    digitalWrite(light, HIGH);
}
else if (strcmp(data, "GOODBYE")==0) {
    digitalWrite(light, LOW);
}
}

Receiver Photon

C/C++

        Particle.publish("Jared", "HELLO");
        delay(1000);
    }
    else if(strcmp(data, "SILENCE")==0){
        digitalWrite(D7,LOW);
        Particle.publish("Jared", "GOODBYE");
