He programs the Arduino bootloader into the chip, and then he’s using the Arduino Leonardo keyboard libraries. Bam! Check out the video below.

The Leonardo is a key element because it is one of the Arduinos that can impersonate a USB keyboard (or mouse) easily. The Due, Zero, and Micro can also do the trick using the Arduino library.

The PCB is connected to the Arduino through a ribbon cable. I used an Arduino Leonardo, which can function as a USB input device. I created the PCB design with the EasyEDA web application.

The Leonardo also trades in the full-sized USB port for one of the micro variety, which will eventually become standard on all Arduino boards. The WiFi, also shipping in October, is a shield that ...

But I can't help but wonder what a determined hacker could put together with an Arduino board, a weekend and a little imagination. Google Reader Pedal: hacking a USB keyboard [Boing Boing] See Also: ...

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 ...
