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!" ...

He builds a simple dead bug Arduino (which he calls an Audioino) using a handful of resistors, a pair of caps, an LED, a reset switch, and most importantly – an audio jack.

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 ...
