“the Arduino language is merely a set of C/C++ functions that can be called from your code”. Where we come from, a bunch of functions written in a programming language is called a library.

We’ve seen a number of graphical, block-based programming languages in our time, most notably Scratch. [David] found a project called OpenBlocks that serves as the basis for Android App Inventor.

The microcontroller on the board is programmed using the Arduino programming language (based on Wiring) and the Arduino development environment (based on Processing).
