Note: This program uses the Parallax Serial Terminal object library, which is included with the
Propeller Tool software download.
Note: To view the results of the demonstration, after uploading is complete run the Parallax
Serial Terminal from the Run menu, or press F12. Momentarily depress the Reset button on the
