Design a night lamp using a LDR and a LED using Arduino Uno and find out the time delays associated in keeping ON the lamp

const int LDR_PIN = A0;    // LDR connected to analog pin A0
const int LED_PIN = 13;    // LED connected to digital pin 13
int threshold = 500;       // Adjust this threshold value based on ambient light conditions
unsigned long lampOnTime = 0;
unsigned long lampOffTime = 0;
void setup() {
  pinMode(LED_PIN, OUTPUT);
  Serial.begin(9600);
}
void loop() 
{
  int lightValue = analogRead(LDR_PIN);
  if (lightValue < threshold && lampOnTime==0) 
  {
    // Turn ON the LED when it's dark and record the start time
    digitalWrite(LED_PIN, HIGH);
    lampOnTime = millis();  // Record the start time
    Serial.print("Lamp ON Time: ");
    Serial.println(lampOnTime);
  } 
  else if (lightValue >= threshold && lampOnTime>0) 
  {
    // Turn OFF the LED when it's bright and record the stop time
    digitalWrite(LED_PIN, LOW);
    lampOffTime = millis();  // Record the stop time
    Serial.print("Lamp OFF Time: ");
    Serial.println(lampOffTime);
    Serial.print("Lamp ON Delay Time: ");
    Serial.println((lampOffTime - lampOnTime)/1000);  // Convert milliseconds to seconds
    Serial.print(" seconds");
    lampOnTime = 0;
    lampOffTime = 0;
  }
