Motion sensor code

C/C++
This is the code that will detect motion from the sensor and send a signal to the other Argon to turn on the light.
int inputPin = D4;              
int ledPin = D7;                
int pirState = LOW;             
int val = 0;
int ledout = D6;
int calibrateTime = 10000;      

void setup()
    {
        pinMode( ledPin, OUTPUT );
        pinMode(inputPin, INPUT);   
        pinMode(ledout, OUTPUT);
        digitalWrite(ledout, LOW);
        Particle.subscribe("Noahs_Argon", myHandler);
    }

void loop()
    {
        if ( calibrated() )
            {
               readTheSensor();
               reportTheData();
            }
    }

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

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

void reportTheData() 
    {
        if (val == HIGH) 
            {
                Particle.publish("3171", "1"); 
                pirState = HIGH;
                setLED( pirState );
                delay(60000);
            } 
            
        else 
            {   Particle.publish("3171","0");
                pirState = LOW;
                setLED( pirState );
                delay(30000);
            }
    }

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

void myHandler(const char *event, const char *data)
    {
        digitalWrite(ledout, HIGH);
        delay(5000);
        digitalWrite(ledout, LOW);
    }

Light Code

C/C++
This is the code that takes the signal received from the motion sensor Argon and turns on the light
int led = D7;



void setup() {

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

Particle.subscribe("3171", myHandler);


}

void myHandler(const char *event, const char *data)
{
if (strcmp(data,"1")==0) {
  digitalWrite(led, HIGH);
  Particle.publish("Noahs_Argon","1");

  }else if (strcmp(data,"0")==0) {
      digitalWrite(led, LOW);

  
}}
