In this section, we will see how to control access via a door. In the last chapter, we saw how to control the lock and the lamps of a house. This project can complement the last one as it will enable you to control the opening of a door, a specific bedroom door, or lights in other rooms.
For this project, we need the following equipment:
Reading TAGS cards
RFID RC522 Module
Arduino Board
The following image shows the RFID tags for reading and controlling the access:
The following figure, shows the RFID card interface for Arduino:
We need to install the <MFRC522.h> library, this file can communicate with and configure the module for reading the tag cards. This library can be downloaded from https://github.com/miguelbalboa/rfid.
