Parking Lot Simulation

hi i am working on a school project that involves a parking lot simulation…

#include <SoftwareSerial.h> 
SoftwareSerial BT(10,11); 

int Disponible=6;
int Ocupado = 7;
int Carros=0;
int Ft_Entrada;
int Ft_Salida;

void setup()
{

  pinMode(Disponible, OUTPUT);
  pinMode(Ocupado, OUTPUT);
  Serial.begin(9600);  
}

void loop ()
{
   Ft_Entrada = analogRead(0);
   Ft_Salida = analogRead(1);
  {
  if(BT.available())
  {
    Serial.write(BT.read());
  }
if(Serial.available())
  {
     BT.write(Serial.read());
     digitalWrite (Disponible,HIGH);
     {

  if (Ft_Entrada == 0)
  {
    Carros++ ;
    Serial.println(Carros);
  }
        if (Carros == 5)
    {
    digitalWrite(Disponible, LOW);
    digitalWrite (Ocupado,HIGH);
    }
    else if (Ft_Salida ==0)
    {
      Carros = Carros-1;
      
      if (Carros != 5)
      {
    digitalWrite(Disponible,HIGH);
    digitalWrite (Ocupado,LOW);
    }
   }
  }
  }
  }
}

Disponible= available
ocupado= occupied
carros= cars
Ft_Entrada= photoresistor entrance
Ft_Salida= photoresistor exit
my proposal is that when the first photresistor counts to 5 the OCCUPIED led will turn on and the AVAILABLE LED will still be lit if a car exits through “PHOTORESISTOR EXIT” or if “PHOTORESISTOR ENTRANCE” doesnt count to 5…
but first the whole project wont start unless im conected to an android device…
the problem is the bluetooth module doesnt appear on the bluetooth aplication…
what am i doing wrong… is it the code… or something else!?
