This project uses an RFID module (RC522) to create an access control system with Arduino. The system checks RFID tags against a stored authorized UID and provides visual and audio feedback based on ...

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 ...

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 ...

Using the RFID starter kit from Elektor provides a good basis to carry out numerous electronic experiments with the Arduino Uno. We show just how simple it can be to realize an application.

[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 ...

Electronics developer and Kickstarter serial entrepreneur Patrick Thomas Mitchell who we have featured numerous times here on Geeky Gadgets has once again taken to the crowdfunding website with the ...

This week Elektor E-zine readers have again an automatic chance of winning a fantastic prize. This time we raffle off an RFID starter kit for Arduino with the accompanying book Home Automation ...

Figure an Arduino most matches the "Other" category. To be specific, it isn't an Arduino brand, it is a DigiSpark, but the trouble isn't with the device itself. The problem is with a buzzer. I got the ...

Planning a game of Hacker Jeopardy at your next meetup? You’re going to want some proper buzzers to complete the experience, but why buy when you can build? [Flute Systems] has released an open source ...
