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 ...

The build settles on an Arduino Pro Micro, as it uses the ATmega32U4 which eliminates secondary USB-to-serial chips, helping cut down on power consumption.

An Arduino Nano or a Micro might be the best options If a small board sounds like the most appropriate choice.

PD Micro is the first Arduino-compatible board with USB Type-C Power Delivery, which allows your project to make use of voltages from 5-20 V. It’s perfect for projects that would require ...

With the Arduino Leonardo, everyone's favorite hackable microcontroller turned a new page. Now it's time to bring that simplified design and slightly expanded feature set to the rest of the family ...

Arduino Micro has some extra leds that it is tricky to programme. Like almost all Arduinos, has a built-in led - the green one on the left in the photo.

Because I have an Arduino Micro (smaller, but almost electrically the same as an Arduino Leonardo), which is built around a different AVR, there are some changes to make. Also, I am trying to ...
