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 ...

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 ...

[Jason] really wanted to build an RFID controlled garage door opener and decided to turn to Arduino to get the job done. For someone who’s never worked with an Arduino before, he really seemed to know ...

We are using the Arduino Uno board, but any SPI board should work given that the wiring is correct and supplies enough power to the MFRC522. In the next section, the native RFID library shipped with ...

[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.

The RC522 RFID module based on MFRC522 IC from NXP is one of the most inexpensive RFID options. It usually comes with an RFID card tag and key fob tag having 1KB memory. And best of all, it can write ...

Serial entrepreneur Patrick Thomas Mitchell has once again taken to Kickstarter to launch his 33rd campaign allowing electronic enthusiasts to back a small yet fast RFID reader. The card reader can be ...
