Barebones MP3 Player

 

Part B. Connect And Test Your Decoder

Describe the tone pattern you hear (i.e., high or low, how long, etc.).

I hear three tones, each separated by 1 second, in a descending frequency.

Part C. Play Some Music!

Tell a member of the teaching team what your song is (or better yet, play it for us).

Absolutely Cuckoo, Baba Yetu, Adiemus, Somewhere Over The Rainbow/What a Wonderful World

Does this code play all the songs in all the directories of the SD card? If not, which songs does it play? How does it keep from playing the text file?

Yes, it plays all the songs.

The program check the suffix of every file.

What are the pros and cons of using this method?

The pro is that it solves the problem that the player pause and then play in one press. The con is that you should have to find a magic number which can solve the problem, which may vary in the button and the user.
