  * @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.
+ * @brief 
  * @version 0.1
