ID System with SMS Notification using RFID MFC2522 RFID and SIM800L GSM Module

In this tutorial, we will learn how to connect Arduino with FRID and GSM Module. This is a cool project that can be used in different scenarios (e.g. School ID system with SMS notification which notifies parents if their child arrived at school; Doorlock system with SMS notification) and many more.

If you have trouble connecting your GSM module, I have a separate tutorial on how to connect your GSM module and send SMS.

 

Installing the MFRC522 Library

After you have connected your Arduino and downloaded the MFRC522 Library Go to “Sketch -> Include Library -> Add .ZIP Library” and browse your downloaded ZIP file.



 

Uploading the Source Code

Upload the following Codes to your Arduino

Replace the ZZ with your country code, followed by your phone number. For example, in the Philippines, ZZ would be 63, followed by the next 10 digits.
