– A door lock mechanism (this can be a simple latch or a more complex lock) First, connect the servo motor to the Arduino Uno. The servo motor typically has three wires: power, ground, and signal.

Connect the 4x4 keypad to the Arduino as per the wiring diagram. Attach the servo motor to the door lock mechanism. Set up the LEDs and buzzer for status feedback. Upload the code to your Arduino and ...

In this project, I designed and implemented a secure, efficient, and user-friendly door lock system using RFID technology integrated with an Arduino Uno microcontroller. The system automates access ...

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 ...

Arduino enthusiasts may be interested in a new gesture controlled Arduino door lock which has been created by Adham Negm and uses an Arduino Uno together with a servo motor to slide the bolt back ...

Perhaps you could create an Arduino device to lean on the door right before the Arduino device bolts the door. It's not clear if the lock unlocks the door when you close that incognito browser.

Today, installing a home security system is a critical study in implementing cutting-edge technology to attain this purpose. One of the most useful technologies to allow remote monitoring of various ...

Using an AVR ATmega168 running the Arduino boot-loader, [pcmofo] has prototyped a two-part design. An RFID reader is mounted outside the door with data wires running to the inside where the ...
