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 ...

The last few years have seen an incredible increase in the marketing for home automation devices. Why this tech is just picking up now is something we’ll never understand – home automation systems ...

Here is a simple general-purpose security alarm circuit built on the Arduino platform. It brings up an obtrusive alert signal when an intrusion/theft attempt is observed by its front-end sensor. In ...

This project turns an Arduino Nano into a fully functional RFID reader/writer device that behaves like a real commercial RFID hardware unit. Instead of acting like a simple Arduino sketch, the ...
