In this tutorial, we will learn how to read and write data to a specific RFID block using MFRC522 and Arduino. If you are storing a person’s first name and surname, then this tutorial is what you are looking for. You can also read the data stored in ID by using the MFRC522 library.
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.
Today we will learn how to send and receive SMS with SIM800L GSM Module and Arduino. This is a great project that you can integrate with your home automation or send sensor readings to your phone using SMS.
