While there are a couple of open-source brushless drivers already available, [neuromancer2701] created his own brushless motor controller on an Arduino shield.

The Arduino has been used for many purposes, and “shields” are available to make many common tasks easier. However, [Nick] wanted a stackable motor driver shield, so he build one himself!.

OMC's H19 fiber-optic shield has been adapted as a stackable add-on for the Arduino Uno. It’s designed to simplify the integration of fiber-optic data links into microprocessor-based platforms.

OMC has launched a fibre optic transceiver shield for Arduino Uno, designed to work with PMMA (polymer) optical cables up to 25m long, plus demonstration software.

In this particular project, I contemplated a shield for Arduino Nano, which can gather weather-related information by a built-in BMP280 Temperature and Pressure Sensor, a photoresistor, and a ...
