Here's a listing saved to an external file that adds Arduino as a language, and highlights all the builtin types and functions properly.
Place arduinoLanguage.tex file in your working directory (next to the LaTeX file you're working on). To add it to your project, place:
\input{arduinoLanguage.tex}
somewhere before \begin{document} in your LaTeX file.
In your document, place your Arduino code between:
\begin{lstlisting}[language=Arduino]
%% arduino code here %%
\end{lstlisting}
Or create your own style to make changes like adding non-built-in functions and variables:
\lstdefinestyle{myArduino}{
language=Arduino,
%% make listing changes here %%
}
And place your Arduino code between:
\begin{lstlisting}[style=myArduino]
%% arduino code here %%
\end{lstlisting}
arduinoLanguage.tex
