First Argon with the PIR sensor

C/C++
Place this Argon and sensor in an area of choice, and let it keep an eye on what kind of human or animal motion is going on in there!
// First photon, Motion sensor by Jeffrey Cecil
int inputPin = D2;              
int ledPin = D5;                
int pirState = LOW;             
int val = 0;        
int calibrateTime = 10000;

Second Argon with Notification LED

C/C++
Keep this Argon handy, in another room, or at the office, to notify you when motion has been detected in your area of interest.
//Buzzer Side by Hal
int led = D7;
int Buzzer = D0;
int state = 0;
int pirState = LOW;
int led2pin = D5;

void setup() {
pinMode(led, OUTPUT);
digitalWrite(led, LOW);
pinMode(Buzzer,OUTPUT);
digitalWrite(Buzzer, LOW);
}


void myHandler(const char *event, const char *data)
{
  digitalWrite(led, HIGH);
  delay(100);
  digitalWrite(led, LOW);
  delay(100);
 
  digitalWrite(Buzzer,HIGH);
  	delay(100);
  digitalWrite(Buzzer,LOW);
 
  digitalWrite(led, HIGH);

  digitalWrite(led, LOW);
  delay(100);
 
  digitalWrite(Buzzer,HIGH);
  	delay(100);
  	digitalWrite(Buzzer,LOW);
