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 ...

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 ...

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 ...

[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 ...

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 ...

A few months back, [John] was reading an article about a simple RFID security system kit, and decided he would like to build one himself. While many of the system’s details, including full schematics ...

Abstract: This paper presents a combination of RFID and robotic technologies for developing a cloth-dressing robot system in the field of robot's body clothing innovation. By using the RFID as key ...
