What is an Arduino? – Microcontroller – Definition

Arduino is an open-source platform used for building electronics projects. Arduino consists of both a physical programmable circuit board and a piece of software, or IDE that runs on your computer used to write and upload computer code to the physical board.

(Arduino Board)


There are many other microcontroller platforms available for physical computing. Netmedia’s BX-24, Parallax Basic Stamp, MIT’s Handyboard, Phidgets, And many others have similar features. All of these tools take microcontroller programming’s messy details and wrap it up in an easy-to-use package. Arduino also simplifies the working process with microcontrollers, but it offers some advantage over other systems for teachers, students, and interested amateurs.


Compared to other microcontroller hardware, Arduino boards are relatively cheap. The Arduino module’s least expensive version can be assembled by hand, and even the Arduino modules pre-assembled cost less than $50.

Arduino Software (IDE) is running on Windows, Macintosh OSX and Linux operating systems. Most of the microcontroller systems are limited to Windows.
The simple, transparent programming environment

For beginners, the Arduino Software (IDE) is easy to use, yet flexible enough for advanced users to take advantage of. It is conveniently based on the Processing programming environment for teachers, so students learning to program will be familiar with the Arduino IDE that works in that environment.
Open-source software

The Arduino software is published as open-source tools, available for extension by experienced programmers. C++ libraries can be expandable language. And those who want to understand the technical details can make the leap from Arduino to the programming language of the AVR C. Likewise, if you want, you can directly add AVR-C code to your Arduino programs.
Open-source hardware

Arduino boards plans are published under a license from Creative Commons. Experienced circuit designers can make, extend, and improve their own version of the module. Even users who are relatively inexperienced can build the module’s breadboard version to understand how it works and save money.

It’s composed of a few main components:

  • The board, which is usually an ATmega or ARM microcontroller
  • The bootloader, which loads code from your computer on to the board
  • The IDE, where you write C/C++-like code for the board
  • The libraries, which provide high-level functions to you like writing digital values to pins or reading analog input

You can do many types of projects and testing using the Arduino Board. Example 3D Printers, Laser Harp, Baker Tweet, LED Cubes, Sensor Project, Image Processing, etc
