The Arduino sketch continually reads an input pin using an internal pull-up resistor to make it logic high with the key switch connecting the signal to ground.

C ‘common sense’ is that the switch/case answer is both faster and makes more compact code because compilers tend to convert these into a jump table. However, the Arduino compiler tends to convert ...

Electronic, Arduino enthusiasts and makers looking for a project to keep them busy this weekend, may be interested in a cool custom switch created by Dave Darko. That requires users to ...

The newly released Arduino Leonardo has a few very interesting features, most notably the ability to act as a USB keyboard and mouse thanks to the new ATmega 32U4 microcontroller. This feature isn&… ...

“Most powerful” Arduino ever has ARM Cortex-A8 chip, runs “full Linux” 3D printers, sensor networks, and advanced automation enabled by Arduino Tre.

The long-awaited Arduino Due just hit the market, replacing the 8-bit, 16 MHz brain of the popular Uno microcontroller prototyping platform with a 32-bit, 84 MHz processor, while augmenting inputs ...

When Arduino unveiled a boatload of new products on Friday, we could have taken the easy route, posted the PR and called it a day. But, since the crew happened to be in town for Maker Faire, with ...
