Connections:-

PIR motion sensor to Arduino

• Pir VCC = Arduino 5V
• pir GND = Arduino GND
• Pir out = Arduino D8

LED to Arduino

• LED (+) = Arduino D13

Code

int led = 13;

int pir = 8;

void setup() {

pinMode(pir, INPUT);

pinMode(led, OUTPUT);

}

void loop() {

  int val =digitalRead(pir);

if(val== 1){

  digitalWrite(led, HIGH);

}else{

  digitalWrite(led, LOW);

}
