If you want to write some fancy interface on your computer with expanded communication to the Arduino, what library should you use?

The correct answer is letter "C": Java.

Explanation:

Arduino is a developmental free software and hardware organization that provides an electronic prototyping platform that allows users to create electronic objects. To write interfaces with expanded communication in the software, the java library must be used with that purpose to fasten the interface functions. Many java libraries can be used such as java. io, java. lang, java. awt or java. util.
