Write a program to interface a PIR motion sensor and an LED with the Arduino. The LED should turn on for 5 seconds whenever motion is detected.

void setup() {
  pinMode(2, INPUT);   // Set PIR sensor as input
  pinMode(13, OUTPUT); // Set LED as output
  Serial.begin(9600);       // Start Serial Monitor
}

void loop() {
  int motion = digitalRead(2);  // Read PIR sensor

  if (motion == HIGH) {               // Motion detected
    Serial.println("Motion Detected!");
    digitalWrite(13, HIGH);      // Turn ON LED
    delay(5000);                      // Keep LED ON for 5 seconds
    digitalWrite(13, LOW);       // Turn OFF LED
  }
