* Created on: January 12, 2022
* Author: Trevor Barnes
/**
* @file main.c
* @author Trevor Barnes
* @brief Main Driver for the Week 5 "Play a Tune" Lab. This program uses a similar menu style to the previous
* lab. The user is given a new option to play 3 different hard coded songs in arrays of "Note" structs,
* provided by the piezoSpeaker.h file.
* Experience: As a former music student I enjoyed working on this lab very much, to the point that I became
* sort of a perfectionist with its implementation. Getting the timer configured and working with the piezo speaker
* was certainly the most difficult and time consuming part. Once I had that figured out though figuring
* out the best note implementation and songs to play was very enjoyable.
