What is Arduino?

Arduino is an open-source electronics platform based on easy-to-use hardware and software. Arduino can be used to develop interactive objects, taking inputs from a variety of switches or sensors, and controlling a variety of lights, motors or other actuators

It’s intended for artists, designers, hobbyists, and anyone interested in creating interactive objects or environments..

Arduino is an open source hardware and software company, project and user community that designs and manufactures microcontroller kits for building digital devices and interactive objects that can sense and control objects in the physical world. Arduino kits are available commercially in preassembled form, or as do-it-yourself (DIY) kits. The microcontrollers are the same as those used in the Arduino kits, but these are preloaded with a bootloader (either the DFU bootloader or an Arduino-specific one) and are usually programmed using a USB-to-serial adapter before being plugged into the target.

The board uses an Atmel 8-bit AVR microcontroller with 16 or 32 KB of flash memory, depending on the model. It is powered via USB or an external power supply. The board can be programmed while connected to a computer via USB, or without a programming device when attached to an AVR ISP/SPI programmer.

Why to Use Arduino? 

Arduino is an easy-to-use hardware and software system that allows anyone to create interactive objects or environments by writing simple programs. Arduino can sense the environment by receiving input from a variety of sensors and can affect its surroundings by controlling lights, motors, and other actuators. The microcontroller on the board is programmed using the Arduino programming language (based on Wiring) and the Arduino development environment (based on Processing). Arduino projects can be stand-alone or they can communicate with software on running on a computer (e.g., Flash, Processing, MaxMSP).

The open-source hardware nature of Arduino allows easy access to its internal circuitry as well as its software protocols. This allows users to expand or possibly build alternative versions of Arduino.
