Welcome to the GitHub repository for the Arduino Door Lock System! In this project, I demonstrate how to build a simple yet effective electronic door lock system using an Arduino. This project can be ...

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 ...

Connect the components as per the wiring diagram. Ensure the RFID module is properly connected to the Arduino's SPI pins. Connect the I2C LCD display to the Arduino's I2C pins (SDA and SCL). Software ...

I’ve always been tempted by the idea of a smart door lock but have never actually taken the plunge, which might explain my recurring interest in the topic… Which is a long-winded way of saying check ...

This simple fingerprint door unlock project using Arduino can be very useful for door security, forensics, crime investigation, personal identification, attendance system and much more. In the future, ...

If the card gets recognized, the Arduino sends a signal to the relay to unlock the solenoid door lock for 10 seconds, Later, it locks the door automatically. To make it more user-friendly, I decided ...
