Learn to build an RFID based attendance system using Arduino with step-by-step instructions, circuit diagrams, and complete code. This $35 DIY project replaces expensive commercial systems with ...

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 ...

Now that the hardware is ready lets move on to the programming section of our rfid door locking system. But before we do that its important to understadn that the Arduino code for this project is ...

This project is open-source and can be freely used for educational purposes. I demonstrate how to build an RFID-based access control system using Arduino! This project integrates an RFID reader (RC522 ...

DIY Authentication System – Circuit Diagram. Fig. 2 shows the circuit diagram of the project, which is built around an Arduino board (MOD1) and EM18 RFID reader module (MOD2). Connect the RFID module ...

This article describes the construction of a simple Arduino RFID Access control DIY (Do It Yourself) Project using Arduino UNO and a RFID reader module (EM-18) to control an LED and a Relay. Circuit ...

This project showcases how to control an LED with an Arduino using an RFID system. The LED toggles between on and off when a recognized RFID tag is scanned. Ideal for simple access control systems, ...
