That code won't even compile, because analogValue is not defined for the loop function.

void loop() 
{
  int sensorValue = analogRead(pinlight);
    delay(1000);
    
  if(analogValue < ANALOG_THRESHOLD)
  {

Start with one of the example programs and make sure you understand how it works before making any changes.

Hint: the function advancedRead() is a bit useless, because it prints stuff but returns no values.
