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 ...

This is a proof of concept for connected office furniture featuring one RFID RC522 module connected to a Arduino Nano ESP32 getting commands from a RFID card and broadcasting the command through Wi-Fi ...

The project uses short delays to avoid multiple quick reads (delay(1500)). There’s a missing 220Ω resistor on the red LED. I just didn't have one so I used a short delay to flash the LED to limit ...
