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 ...

In this project the RFID systems reader will read the unique ID number (UID) of the RFID tag, recognize the type of the RFID tag and display the information through the I2C LCD1602 display. In this ...

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 ...

RFID (short for Radio Frequency Identification) tagging is an ID system that uses electromagnetic waves in radio frequency to transfer data. A simple RFID system consists of just two components: the ...

Arduino RFID projects have become increasingly popular in recent years due to the simplified technological mechanisms provided by the Arduino platform. The integration of RFID technology with Arduino ...

RFID technology identifies objects using a unique identifier through an RFID tag and reader system. RFID tags can be read-only, with fixed identifiers, or read and write, allowing information updates.

[Matt] has mixed up a batch of two RFID reading door lock systems. While the “door lock” part of the setup has yet to come into existence, the “RFID reading” section is up and running. By using the ...

The use of Radio Frequency IDentification (RFID) technologies is growing. Many different applications are implemented in various sectors, and used for very different purposes. RFID enables wireless ...

[Pierre] recently bought his first car and decided to make his own RFID electric starter for it! An Arduino Nano controls two relays which in turn can turn the car on, start it, and turn it off.
