What is an Arduino Board?

Arduino is a one type of microcontroller board, that is used to design various electronic 

projects. The board includes an Atmel microcontroller, power supply, USB port to connect with a personal computer, an integrated development environment or a pre programmed microcontroller, which are used to write the program and upload into the Arduino board. This board does not necessitate a separate programmer to dump the program into the board and also additionally we can use a USB cable.

Basically, an Arduino board employs the architecture of the Harvard due to separate memory for data and program code. The data of the Arduino board stored in data memory, whereas code of the Arduino board is stored in the program. The types of the Arduino board mainly include Arduino Uno, Arduino mega, Arduino LilyPad, Arduino BT, Arduino Nano and Arduino Mini. Most of the Arduino devices include the components like pins, power, reset button, TX RX LEDs, voltage regulator and power LED indicator.The advantages of these boards include extensible hardware, inexpensive, simple and clear programming environment.
