Obsługa LCD:

#include <LiquidCrystal_I2C.h>

LiquidCrystal_I2C lcd(0x27, 16, 2);


void setup() {
  lcd.init();
  lcd.backlight(); 
  lcd.print("Hello!!!");
}

#include <LiquidCrystal_I2C.h>

   Example sketch/program showing how to read new NUID from a PICC to serial.
   --------------------------------------------------------------------------------------------------------------------
   This is a MFRC522 library example; for further details and other examples see: https://github.com/miguelbalboa/rfid

   Example sketch/program showing how to the read data from a PICC (that is: a RFID Tag or Card) using a MFRC522 based RFID
   Reader on the Arduino SPI interface.

   When the Arduino and the MFRC522 module are connected (see the pin layout below), load this sketch into Arduino IDE
   then verify/compile and upload it. To see the output: use Tools, Serial Monitor of the IDE (hit Ctrl+Shft+M). When
   you present a PICC (that is: a RFID Tag or Card) at reading distance of the MFRC522 Reader/PCD, the serial output
   will show the type, and the NUID if a new card has been detected. Note: you may see "Timeout in communication" messages
   when removing the PICC from reading distance too early.
