Part B. Connect And Test Your Decoder


Describe the tone pattern you hear (ie, high or low?  how long? etc)


Plays three tones, high, medium, low, repeatedly at one second intervals. HIGH -> PAUSE -> MEDIUM -> PAUSE -> LOW -> PAUSE -> HIGH -> ...


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


Mahna Mahna - Muppets


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?


Only plays .mp3 files. 


Draw us a quick sketch of what your circuit looks like.


3V -> 10K resistor -> button -> G


What are the pros and cons of using this method?


Debouncing removes noise from button signal by only registering high and low states. However, if pressed in fast succession, the button may "skip" and not register a button press from the delay in the debouncing process.
