Sick of using those old keys to get into your house? Redditor charmonkie shows off a homemade, keypad-powered deadbolt without actually modifying the door on his apartment. The setup includes a ...

(keypad: columns and rows switching) So now you can see how the button presses can be translated into electrical data for use with a microcontroller. We can now start the real experiment with as ...

The hack is still pretty hardware intensive, but Arduino fans will love this clever hack—especially if you're the type that locks yourself out of your room a lot.

[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 … ...

This project is designed for use with an Arduino Pro Micro and a 4x4 keypad matrix. The code enables the Arduino to read input from the keypad and emulate keyboard input, sending keystrokes to 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 ...

Compared to the computer interfaces of today, the display keyboard used by the Apollo astronauts aboard their spacecraft might look quaint — until you recall that it was central to flying to the ...

In this project, we'll go over how to interface a 4x4 membrane keypad with an Arduino microcontroller. By the end of this tutorial, you'll be able to read the state of the keypad and determine which ...

Here’s how it works. S&T GeoTronics is marking the 50th anniversary of Apollo 11 with an open source, Arduino-based functioning replica of the Apollo Guidance Computer display keyboard, or DSKY.
