Hello!! :slight_smile: I have a problem with my programm that i canot fix it!!This is my program :

I am trying to open with diferrent cards,diferent doors but i dont know how!! I am using relays and an antena and cars but i cannot do it to open different doors with different keys!For example with one key it will open specific door and no other and with another key it will open another diferent door!!
Can you please help!!!I would be gratefull!!! THANK YOU!!! :slight_smile:

The name of each card is different.

#include <PN532.h>
#include <SPI.h>

#define PN532_CS 10
PN532 nfc(PN532_CS);
#include <LiquidCrystal.h>


LiquidCrystal lcd(7, 6, 5, 4, 3, 2);
unsigned long int simdikiid=0;
unsigned long int oncekiid=0;
unsigned long int sayi=0;

int tek=0;
void setup(void) {
  pinMode(8, OUTPUT);
  lcd.begin(16, 2);
   lcd.print("read id");
   delay(500);
   
  Serial.begin(9600);
  
  nfc.begin();


}
  

void loop(void) {
  uint32_t id;

  id = nfc.readPassiveTargetID(PN532_MIFARE_ISO14443A);
if(id!=0){

simdikiid=id;

if(simdikiid!=oncekiid){
  
sayi=sayi+1;
lcd.clear();
lcd.setCursor(0, 0);  
 lcd.print("ID NO=");
lcd.setCursor(7, 0);  
lcd.print(id);
Serial.println(sayi); 
Serial.println(id); 
lcd.setCursor(0, 1);  
 lcd.print("EVET");
 lcd.setCursor(5, 1);
lcd.print(sayi);
digitalWrite(8, HIGH);
delay(100);
digitalWrite(8, LOW);
  


  
  
}

oncekiid=simdikiid;
}
