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 ...

[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 ...

This repository explores the interfacing of 4x4 keypad with an Arduino, but without using any built-in headers. The goal is to completely learn the interfacing mechanism from scratch. The code is ...

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 ...

The arduino client, which just receives the display menu and sends keypresses. The python server, which executes everythin else. Main idea is to craft a steamdeck-like with a 3d printer and crappy ...

Meet the Arduino Esplora, an open source Arduino Leonardo based gaming pad that can be used in DIY Gaming projects, to control robots or just about any other project where a hand held controller is ...

Picture this: You draw or write something on your iPod touch, and it instantly shows up on a wireless display that’s linked to your iPod touch over a web connection. That’s exactly what young engineer ...

Of all the Arduino projects we've seen 'round here, this is certainly one of them! Using nothing but a Graphics LCD, an Arduino, and a WebSocket server he wrote using Python / Tornado, this young ...

The reprogramming of the Lily main board was easily allowed by the USB to UART board that does not require the need for soldering. The Lily Pad main board is using the FT232RL integrated circuit from ...
