This example shows how to use the tone() command to generate notes. It plays a little melody you may have heard before.
The code below uses an extra file, pitches.h. This file contains all the pitch values for typical notes. For example, NOTE_C4 is middle C. NOTE_FS4 is F sharp, and so forth. This note table was originally written by Brett Hagman, on whose work the tone() command was based. You may find it useful for whenever you want to make musical notes.

To make the pitches.h file, click on the "new Tab" button in the upper right hand corner of the window. It looks like this:
Then paste in the following code:
and save it as pitches.h
