An Arduino Leonardo is pressed into service for this hack. With its USB HID capabilities, it’s perfectly suited for custom keyboard builds.

Arduino enthusiasts may be interested in a new thumb-sized radio-equipped Arduino Leonardo development board created by Doug Lyon.

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 ...

Arduino hackers, hobbyists and developers that are looking for a smaller less expensive Arduino Leonardo compatible development board, might be interested in the Lil’ Nardo.

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

Timer4 on the ATmega32U4 (Arduino Leonardo, Micro, Pro Micro) is another one of Microchip/Atmel’s high-speed timers that can be fed by a PLL (phase-locked-loop) multiplied version of the 16MHz system ...

For example, ATmega328P (Figure 13-2, Arduino Uno and Nano) and ATmega32U4 (Figure 10-2, Arduino Leonardo, Micro or Pro Micro) Arduinos have hysteresis built into the input side of digital IO pins (as ...

When the Arduino sees the pin change from high to low, it sends out a keyboard command consisting of the Windows Key and “L”, which is the keyboard shortcut for locking the computer.
