What is an Arduino board?

Arduino board is an open-source programmable circuit, consisting of microcontroller, and many other electronic components.
The board is flexible, low-cost board, and equipped with sets of digital and analog input/output pins, and can be connected to the computer directly via a USB cable.
The Arduino board was designed to create interactive objects or environments. This board can be use into a variety of electronic projects. And can interact with motors, Leds, sensors, buttons, speakers, cameras, internet, smart-phone, and tv …etc.

Arduino boards types:

there are many types of Arduino boards, which differ from each other through the shape, size, and number of input/output pins, speed, voltage, but they are doing the same tasks.
