PIR sensor Interface with Arduino

const int PIR_Sensor = 2;     // the number of the PIR_Sensor pin
const int ledPin =  13;      // the number of the LED pin
int Motion_State = 0;         // variable for reading the Motion status

void setup() {
  pinMode(ledPin, OUTPUT);    // initialize the LED pin as an output:
  pinMode(PIR_Sensor, INPUT); // initialize the PIR_Sensor pin as an input:
}

void loop() {
  
  Motion_State = digitalRead(PIR_Sensor);  // read the state of the PIR_Sensor value:
  if (Motion_State == HIGH) {   // check if the Motion_State is High.
  digitalWrite(ledPin, HIGH); // turn LED on:
  delay(10000);
  } else {
    
    digitalWrite(ledPin, LOW);  // turn LED off:
  }
