Included in this repository are five sketch files, outlined below. The sketch file to use depends on what board you will be usinf (Arduino Uno (or compatable) or Arduino Mega (or compatable). There ...

The Automatic Entry System is an embedded project designed to control access to a restricted area. It uses an Arduino Mega with a non-blocking state machine, RFID module, SD card storage, and other ...

Radio Frequency Identification is widely used in contactless payment cards, National Highway Tollgate systems, and in security passes. By integrating an RFID reader with an Arduino, you will be able ...

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 ...

Arduino RFID projects have become increasingly popular in recent years due to the simplified technological mechanisms provided by the Arduino platform. The integration of RFID technology with Arduino ...

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 ...

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 ...
