Actually I don't know about Arduino, but seeing my fellow classmates, I want to start learning it. Could anybody tell what actually Arduino is about?

A popular Arduino - The Arduino Uno:

In case I get accused of writing a "link-only" answer ...

The Arduino is a hobbyist prototyping platform, where users can develop projects for microprocessors. Typically the boards have one or two processors on them, can connect to a PC/Mac/Linux by a USB interface, be programmed in C++, and operate external devices (eg. motors, lights, MIDI, LCD screens, LEDs) and take readings (eg. temperature, time, location, voltage).

Different boards have different capabilities, such as the number of I/O ports, the amount of memory, and the size of the program that can be uploaded.

You can connect them to the major operating systems:

  • Linux
  • Macintosh
  • Windows

The hardware and software are open-source, making development for them easy.
