While newer Arduinos and Arduino compatibles (including the Hackaday.io Trinket Pro. Superliminal Advertising!) either have a chip capable of USB or rely on a V-USB implementation, the old fogies o… ...

This set of microcontroller boards start around $25 and come in the smallest footprint made by Arduino, allowing you to build compact and portable devices that are more difficult to make with an Uno.

This Arduino-based Pomodoro timer project also uses this 25-minute cycle. Once you push the button to start the timer, it will run for 25 minutes, display a count-up timer and a "Study time!" ...

[Chris] wrote us to share a neat technique he has been using to program the Arduinos he uses in his projects. He likes to build bare bones Arduino clones rather than sacrifice full dev boards, and ...

The Arduino Due has a 32-bit ARM core (the Uno is 8-bit), an 84 Mhz CPU clock, 96 KB of SRAM, and more USB ports than the Uno. In short, it's a much more powerful microcontroller that can handle a ...
