Arduino consists of two parts: hardware (various models of Arduino boards) and software (Arduino IDE). The hardware part is an Arduino PCB that can be used to connect circuits; the software part is the open-source and cross-platform Arduino IDE (written in Java, based on Processing programming language and other open-source software) - your programming environment in computer that can be used with any Arduino boards. All you have to do is write the code in Arduino IDE, and upload it to the Arduino development board, then the program will tell Arduino PCB what to do and how to do.
