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 ...

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 ...

[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 ...

An IoT-based automated toll collection system using RFID technology, Arduino Uno, Node.js, MongoDB, and Servo Motor. Designed to reduce traffic congestion and manual errors at toll plazas by enabling ...

[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.

Metro smart automated systems always look cool to us. You can scan and rescan to travel just using a MetroCard. No need for special personnel or anything—just ...

Abstract: The concept of Smart Trolley improves the shopping experience by automating various processes by using RFID or Radio Frequency Identification technology. It comprises RFID tags for the items ...
