Components/Equipment Required:

            Following Components/Equipment are required to perform task.

1.    Arduino Uno (https://piees.pk/product/arduino-uno-r3/)

2.    PIR Sensor (https://piees.pk/product/pir-sensor/)

3.    Buzzer/LED Light 

4.    Breadboard

5.    Jumper Wires (https://piees.pk/product-category/jumper-wires/)

Circuit Diagram:

Arduino Program:

int PIR = 8;

int LED = 13;

void setup() {

  pinMode(PIR, INPUT);

  pinMode(LED, OUTPUT); 

}

void loop() {

  int PIRValue = digitalRead(PIR);

  if (PIRValue == 1) {

    digitalWrite(LED, HIGH); // The Relay Input works Inversly

    delay(100);

     digitalWrite(LED, LOW); // The Relay Input works Inversly

  }

  if (PIRValue == 0) {

     digitalWrite(LED, LOW); // The Relay Input works Inversly

  }}
