Arduino RFID Door Lock Circuit Diagram. EM-18 RFID Reader: RFID stands for Radio Frequency Identification.Each RFID card has a unique ID embedded in it and a RFID reader is used to read the RFID card ...

When the power is disconnected the slug moves outside and locks the door. It doesn’t use any power in a locked state. To drive the solenoid lock you would need a power source that can give 12V @ 500mA ...

With this technology, the device can be configured to authenticate and then set selected functions, such as a login system or attendance system. The EM 18 RFID module is used to read the RFID tags and ...

An RFID reader and Arduino run the system, with a button inside to unlock the door. But if power were to fail, you will still be able to get in or out manually.

The system's three most important components are an electrical locking mechanism, an Arduino microcontroller, and an RFID reader module. The RFID reader will verify the card's validity, and then the ...

This is an IoT-based system with Radio Frequency Identification System which supports door lock and unlock function. This door locking system helps registered users to lock or unlock the door. The ...

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 ...

Learn how to build an RFID door lock system using Arduino for secure and smart access control. This step-by-step guide covers circuit connections, coding, and hardware setup to create an automated ...
