An Arduino Nano controls two relays which in turn can turn the car on, start it, and turn it off. Instead of adding a button for “push to start” he opted for a 13.56MHz RFID module.

A cool RFID music table has been created using Arduino, iPod, and RFID tags to make it easy to change albums by simply changing the RFID tag. Each RFID tag has an individual code number relating ...

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 ...

This tutorial will guide you through the process of building a tachometer around an Arduino. Tachometers are used to measure rotation rate in Revolutions Per Minute (RPM). You don’t need much… ...

Instructables user talk2bruce created the Arduino Internet Gizmo, a card reader that takes you to your favorite websites with a touch of an RFID tag.

I am guessing that you have an Arduino Uno board handy. Even though most of the available libraries (for PN532) are focused primarily on Arduino Mega, I still prefer the Uno, as it’s more comfortable ...

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 ...

Tronixstuff has a borderline insane tutorial series going, and as of now, 27 chapters have been published. It's essentially the Arduino Bible, but the two most recent additions in particular have ...
