Explain connection (GND/PIN 13/3.13 v) For this code (Light Sensor arduino):

 

const int ledPin = 13;

const int ldrPin = A0;

void setup() {

  Serial.begin(9600);

  pinMode(ledPin, OUTPUT);

  pinMode(ldrPin, INPUT);

}

void loop() {

  int ldrStatus = analogRead(ldrPin);

  if (ldrStatus <= 400)

  {

    digitalWrite(ledPin, HIGH);

    Serial.print("Its Dark, Turn on the LED:");

    Serial.println(ldrStatus);

  }

  else

  {

    digitalWrite(ledPin, LOW);

    Serial.print("Its Bright, Turn off the LED:");

    Serial.println(ldrStatus);

  }

}
