 [Arduino](https://en.wikipedia.org/wiki/Arduino) is an open-source electronics company who have developed mutliple microcontrollers that allow users to create projects by connecting various sensors, actuators, and other input/output devices and programming them with the `C++` programming language. The Arduino Uno is a development board that utilizes the `ATmega328P` microcontroller from the Atmel AVR family.
