RFID MRC-522 (Home security)

Im sorry, I forgot to explain beforehand how the project went,
So I want to make, if the rfid scanner scans the correct rfid tags, it will trigger a servo motor (assuming as the door lock), and if the rfid scanner scans for the wrong rfid tags, it will trigger an alarm in the mp3 module (in my case yx5300)
is it possible to make it like that?

I found this article , hopefully it’s an example of the right project

I’ve read this project , but it’s using a different rfid scanner and mp3 module. What should i do now ?
