An Arduino is a popular open-source single-board microcontroller. Learn how to program one and let the possibilities take shape.

The Java program can also read an Arduino program file and convert all the print calls in it to use the library, if you like. As you might expect, this requires some cooperation from your program.

To the average Arduino user, some of this is irrelevant, maybe most of it, but the language still gives us some nice features that we can take advantage of as we program our microcontrollers.
