This project presents the design and implementation of a secure and user-friendly RFID and keypad-based door lock system using Arduino The system integrates two authentication methods: RFID (Radio ...

This project implements a secure password-based unlocking system using an Arduino Nano, featuring motion detection via a PIR sensor, password input through a 4x4 matrix keypad, and user feedback via a ...

If you want to add a keypad to your Arduino project, the options are pretty limited. There’s that red and blue 4×4 membrane we’ve all seen in password-protected door lock projects, and the phone ...

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 ...

The ARDUINO IDE associated with the ARDUINO board uses specific numbering, assigning numbers from 0 to 19 to digital pins 0 to 13 and numbers A0 to A5 to analog pins. GCBasic directly manipulates the ...

Arduino is a good platform if you want to start working with electronics. The platform, specifically the Arduino Nano family, is a set of small form-factor boards that act as microcontrollers, meaning ...
