What is Arduino and its history

In a nutshell, an Arduino is a development board that can be used by tinkerers, hobbyists, and makers to design and build devices that interact with the real world. While Arduino refers to a specific type of board design, it can also be used to refer to a company that manufactures a specific implementation of these boards and is typically also used to describe the community around compatible boards made by other people or companies which function in a similar way.
