Complete Arduino RFID tutorial using RC522 module. Learn wiring, programming, and build practical projects like door locks. Code examples included.

Arduino library for MFRC522 and other RFID RC522 based modules. Read and write different types of Radio-Frequency IDentification (RFID) cards on your Arduino using a RC522 based reader connected via ...

This code is an academic work for SENAI SP Brazil developed in embedded system course. It utilizes MFRC 522 library and proposes to read just one byte of RFID TAG compatible with MFRC522 in order t ...

The read/write device consists of a Radio Frequency module and an antenna that generates a high-frequency electromagnetic field while the tag is usually a passive device that contains a microchip that ...

– MFRC522 connection header: This is where the MFRC522 RFID reader connects to the main board. – Program select header: Currently, only header#1 is being used in the program.

I just received my RC522 RFID reader and made this simple Arduino access control system that uses the reader, a buzzer for the alarm and a relay shield for the security system. The relay can be used ...

Therefore, an effort was made to design a tool for “identification of impedance changes in metals using an Arduino Uno-based RFID RC522” which is relatively inexpensive and easy to carry.

Meet the Arduino Compatible RFID Reader Module. It can hold card data for up to five cards, takes seconds to program, and holds card data in EEPROM memory, which means that the cards are saved ...
