Arduino is a project, open-source hardware, and software platform used to design and build electronic devices. It designs and manufactures microcontroller kits and single-board interfaces for building electronics projects.
The Arduino boards were initially created to help the students with the non-technical background.
The designs of Arduino boards use a variety of controllers and microprocessors. The Arduino board consists of sets of analog and digital I/O (Input / Output) pins, which are further interfaced to breadboard, expansion boards, and other circuits. Such boards feature the model, Universal Serial Bus (USB), and serial communication interfaces, which are used for loading programs from the computers.
It also provides an IDE (Integrated Development Environment) project, which is based on the Processing Language to upload the code to the physical board.
The projects are authorized under the GPL and LGPL. The GPL is named as GNU General Public License. The licensed LGPL is named as GNU Lesser General Public License. It allows the use of Arduino boards, it's software distribution, and can be manufactured by anyone.
