|
* @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.
