Even with more and more devices making the leap to USB-C, the Arduino Uno still proudly sports a comparatively ancient Type-B port. It wouldn’t be a stretch to say that many Hackaday readers ...

The idea early on was to leverage existing Arduino libraries to connect with a standard USB mouse, specifically, the hardware would take the form of an Arduino Mega 2560 with a USB Host Shield.

A simple Arduino project to measure the stability of USB power supplies. This project can easily be reconfigured to be a simple digital voltage meter.

Options to power the Arduino Nano include USB, VIN, and 5 volt pin, meaning you have power options for almost any situation.
