Inside is Arduino Pro Micro and a PMW 3389 optical sensor on a breakout board. [Ben] was going to use flexible 3D printed panels as mouse buttons, but then had an epiphany — why not use keyboard ...

Except, on the Micro, there is no actual serial bus involved in programming the Arduino, as everything is done over USB. So the TX and RX leds are driven by a couple of pins on the ATmega32U4 (see a ...

Introduction This firmware (arduino pro micro sketch) is intended for small productions of commercial leds based devices. It is compatible with ATmega32U4 with Arduino bootloader (Arduino pro micro, ...

This Arduino ICSP programmer has been made from Alumide, a strong plastic with aluminum fibers. The cover is made from translucent POM, illuminated by three rings of in total 27 LEDs.

The Arduino Micro will be available exclusively through Radio Shack and Adafruit first before becoming more widely available next month. The board is available with headers for €21 (roughly $27 ...

Other features include a 16GHz crystal oscillator, an ICSP header, and, of course, a reset button. There are code libraries for emulating the device via USB-HID as a keyboard, for example, or a mouse.

To overcome these concerns, this work proposes an Arduino based Pro Micro Versa USB, which utilizes the Arduino ATmega32u4 chip, a versatile 8-bit microcontroller from Microchip Technology, housed ...
