How to program a LCD to this HID Reader Code

Hi

I'm a arduino beginner.

I'm working on the project attached in the link.

https://create.arduino.cc/projecthub/shakataganai/hid-prox-rfid-to-arduino-bd9b8a?ref=search&ref_id=hid&offset=1

Please someone help me how to print the same message in a LCD display what shows in the serial monitor when I swipe a card.

I want to know how to update this code and pin connections to fix a 16x2 LCD display.

Please help as this is really urgent. Thanks.

We don't like "urgent" requests here when the urgency is not explained.. let's say it's still Xmas...

The display of the card is done here

void printBits() {
      Serial.print("FC = ");
      Serial.print(facilityCode);
      Serial.print(", CC = ");
      Serial.println(cardCode);
...

so basically you would put your LCD display code in the printBits() function and do

void printBits() {
      Serial.print("FC = ");
      Serial.print(facilityCode);
      Serial.print(", CC = ");
      Serial.println(cardCode);

      // assuming lcd is the variable holding the instance of the LiquidCrystal Library (or other) class connected to your LCD
      lcd. setCursor(0,0); // 1st line 1st col
      lcd.print("FC = ");
      lcd.print(facilityCode);
      lcd. setCursor(1,0); // 2nd line 1st col
      lcd.print(", CC = ");
      lcd.print(cardCode);
...

of course you need to properly declare and configure your lcd to work - you can figure that out by reading about LCD and arduino (and you might have to handle erasing some characters if you display many times with various data lengths)
