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 ...

Put aside all of the projects that use an Arduino to blink a few LEDs or drive one servo motor. [IngGaro]’s latest project uses the full range of features available in this versatile microcontroller ...

[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 ...

An RFID-based attendance system transforms the tedious task of manual attendance tracking into an automated, error-free process. What makes this project particularly exciting is how a few inexpensive ...

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 ...

The system operates seamlessly: the user initiates the process by scanning their tag with the RFID module, acting as the RFID reader. If the tag matches an entry in the Arduino's database, ...

An Arduino project implementing a security alarm system featuring PIN code access via a 4x4 keypad, status updates on a 16x2 LCD, motion detection using an HC-SR04 ultrasonic sensor, and ...

If you can dream it, Arduino can help you build it -- perhaps with a dash of MakerBot thrown in for good measure. The latest homebrew project to hit the ol' inbox sounds an alarm whenever you leave a ...

Dejan Nedelkovski has built a stylish DIY touchscreen Arduino music player and alarm clock which has been created using a folded piece of sheet metal to provide a minimalist yet clean enclosure to ...

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 to ...
