The Arduino Compile Phase So we’ve got C/C++ code. Compiling it into an Arduino project is surprisingly straightforward, and it’s well-documented in the Arduino docs wiki.

The Code Kit is an Arduino system in a box. It comes with a small rechargeable battery that can power an Arduino-based CodeBit with three inputs and three outputs.

“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.
