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.

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,… ...

Did you know that you can use Arduino to turn on an LED when you press a button? Well, it is true, you can do this! Leaving the joke aside, let me show how you can achieve this. You will need the ...

You can read the state of a button using Arduino and a few lines of code. The actual state is shown in the Serial Monitor window as 0 or 1, 0 meaning the button is not pressed and 1 that the button is ...

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.

This year at CES, Intel introduced Curie — a button-sized system-on-chip module made for low-power wearables — but the company was mum on what would be the first products to use it. Now we ...

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 ...
