Component List :
1. Arduino Uno
2. Breadboard
3. LED x1
4. Resistor x2
5. Piezo Buzzer
6. PIR Sensor

CODE :

int ledPin = 13;
int inputPin = 8;
int pirState = LOW;
int val = 2;
int piezoPin = 12;

void setup()
{
pinMode(ledPin, OUTPUT);
pinMode(piezoPin, OUTPUT);
pinMode(inputPin, INPUT);

Serial.begin(9600);
}

void loop()
{
val = digitalRead(inputPin);
if(val == HIGH){
digitalWrite(ledPin, HIGH);

digitalWrite(ledPin, HIGH);
tone (piezoPin, 1000, 500);

if (pirState == LOW){
Serial.println("Ade pergerakan!");

pirState = HIGH;
}
} else{
digitalWrite(ledPin, LOW);

if(pirState == HIGH){
Serial.println("Tiada Pergerakan!");
pirState = LOW;
}
}
}
