The RFID reader communicates with the Arduino through the SPI protocol and different Arduino boards have different SPI pins. To test if the RFID reader is working properly or not, upload the “dumpinfo ...

This project implements a password-protected electronic door lock system using an Arduino microcontroller. A 4×4 matrix keypad is used to enter the password, while a 16×2 I2C LCD provides system ...

[Andrea] just sent us this great student hack he made for his room. He’s constructed an Arduino keypad door lock — without using any proper fastening hardware! The entire build is made out of scrap ...

A keypad is one of the most commonly used input devices in microprocessor applications. In a standard keypad wired as an X-Y switch matrix, normally-open switches connect a row to a column when ...

Abstract: This system presents the design and implementation of a password-based door lock system integrated with LED light control for enhanced security. The proposed system allows password entry ...

Abstract: In an era where homeowners frequently leave for work or education, robust security for residences is imperative. Traditional security measures, including window and door locks, present ...

Electronic and Arduino enthusiasts searching for an Arduino project to keep them busy this weekend may be interested in a new Arduino Mega fingerprint door lock. Using a little Arduino programming the ...

Arduino enthusiasts or those looking to learn more about programming with Arduino and electronics-in-general may be interested in a new Kickstarter campaign and Arduino compatible 42-Digit SPI Keypad ...

/:16 We've shown you what one clever hacker did to work his door with a keyfob, and this year that same student is back with a variation, based on a keypad. The hack is still pretty hardware intensive ...
