Arduino is mainly composed of two parts:

• Hardware
• Software.

The hardware is an Arduino board which contains a microcontroller.

The Arduino programming language is used in the Arduino Software (IDE) to send instructions in a form of a program to the Arduino board.

• The input/out pins of the microcontroller is controlled via the uploaded program.

We often connect the Arduino board to the PC via a USB port. The program is written in the software IDE, complied, and finally uploaded to the board. A simple example is to turn ON and OFF an LED (Light Emitting Diode) that is connected to the Arduino board. You can download the Software IDE from Arduino Software
