Common examples of such devices intended for beginner hobbyists include simple robots, thermostats and motion detectors. The Arduino project began in 2005 as a tool for students at the Interaction Design Institute Ivrea, Italy, aiming to provide a low-cost and easy way for novices and professionals to create devices that interact with their environment using sensors and actuators. In addition to using traditional compiler toolchains, the Arduino project provides an integrated development environment (IDE) and a command line tool developed in Go. The microcontrollers can be programmed using the C and C++ programming languages, using a standard API which is also known as the Arduino language, originated from the Processing language. The boards feature serial communications interfaces, including Universal Serial Bus (USB) on some models, which are also used for loading programs. The boards are equipped with sets of digital and analog input/output (I/O) pins that may be interfaced to various expansion boards ('shields') or breadboards (for prototyping) and other circuits. Arduino boards are available commercially from the official website or through authorized distributors.Īrduino board designs use a variety of microprocessors and controllers.

Arduino ( / ɑː r ˈ d w iː n oʊ/) is an open-source hardware and software company, project, and user community that designs and manufactures single-board microcontrollers and microcontroller kits for building digital devices.
