While you hopefully don't need one-button access to 911, a desk-mounted panic button is undoubtedly cool, and it makes for a great DIY Arduino project ...

Running out of GPIO pins? Learn how to connect multiple buttons to just one Arduino pin using clever wiring and resistor techniques. Perfect for compact projects, keyboards, or when using small ...

Earlier this year we showed you a slick MIDI sequencer project that was constructed using an Arduino Mega, which also happened to drive an incredibly detailed touch screen display.

The OONTZ uses a 3D printed case, a 16 button keypad, an Arduino Leonardo, a monochrome driver, and a few potentiometers. It's actually a pretty simple thing to build yourself provided you can the ...

Arduino pins, and almost everything else at a standard hobbyist scale, are 0.1" pin spacing - so I just soldered the sense wires to some 0.1" headers I have laying around.

The button states could easily be read by using an Arduino’s analog input. A Pro Mini model was chosen for its small size as it could be housed in the radio compartment of the dash.

Nearly every home-built project we cover uses Arduino somewhere, and the open-source microcontroller system is now out of the beta stage, having reached the version 1.0 milestone.
