Here’s a no-PCB Arduino that doesn’t obscure the DIP footprint of the AVR chip. It’s built on an ATmega88 chip, and includes a programming header, reset button, a couple of filtering caps ...

so I built her a "Button Box" based around an Arduino. Open source ... deal with is really demanding on a voltage rail, and filter caps are cheap. The backside is another one of those solder ...

a desk-mounted panic button is undoubtedly cool, and it makes for a great DIY Arduino project. You'll need a prepaid SIM card, an Arduino, a GPRS shield, and a few other odds and ends. Luckily ...

[Ed] was tasked with adding push-button degaussing ... to the power supply decoupling cap to power the new deguassing circuit and connected the SSR to the Arduino as an open collector input.

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 ...

but it can be improved with this DIY build that lets you launch ships with a giant red button. Based on an Arduino Micro, this project gives you a small control panel with two buttons. The smaller ...
