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 ...
I2C or inter-integrated circuit is a communication protocol which is very efficient. With it, one master can communicate to multiple slaves using just two pin, namely the SDA and SCL. It is a serial ...
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 ...
Makers and developers that enjoy creating projects using the Arduino platform may be interested in a new shield for Arduino that incorporates an LCD JEMshield++, keypad and enclosure all in one. JEM ...
[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 ...
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 ...
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 ...
Arduino is a very popular open-source platform and Arduino UNO is one of the most loved microcontrollers among electronics hobbyists worldwide. It consists of a physical programmable circuit board and ...
