Berikut programnya;
//inialisasi pin PIR sensor
const int pinPir = 2;
//inialisasi pin buzzer
const int pinBuzzer = 3;
//inialisasi pin saklar
const int pinTombol = 4;

//inialisasi nilai awal state
int state = 0;

void setup()
{
//inialisasi status I/O masing2 pin
pinMode(pinPir, INPUT);
pinMode(pinBuzzer, OUTPUT);
pinMode(pinTombol, INPUT);

//inialisasi nilai awal masing2 pin
digitalWrite(pinPir, LOW);
digitalWrite(pinTombol, LOW);
}

void loop()
{
//buzzer/alarm mati
digitalWrite(pinBuzzer, LOW);
}

//jika saklar dimatikan, maka
else
{
//jika nilai state = 0, maka
if (state == 0)
{
//buzzer/alarm mati
digitalWrite(pinBuzzer, LOW);
}

//jika nilai state = 1, maka
else if (state == 1)
{
//buzzer / alarm menyala
digitalWrite(pinBuzzer, HIGH);
}

//jika PIR mendeteksi ada oarng/objek, maka
if (digitalRead(pinPir) == HIGH)
{
//niali state menjadi = 1, dan buzzer/alarm berbunyi
state = 1;
}
}
