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 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 ...

Abstract: Among the many potential applications of inexpensive radio frequency identification (RFID) technology are security, tracking assets, people monitoring, supply recognition, and access control ...

One uses the LiquidCrystal_I2C library (I²C display). The other uses the LiquidCrystal library (parallel display). In the code, set: USE_I2C = 1 for I²C displays (with LiquidCrystal_I2C) USE_I2C = 0 ...
