# sasa-chairs
# Note: This was demo code set up to show students how the debounced button press doesn't register until
# after the song plays. However for some reason I notice when run on a CPB using CircuitPython 9.2.4
# that the song runs a second time, even after the update() has run, the button_B is pressed, and 
# button_A: False, button_B: False prints <- not expected because my finger remains on button_B.
# Here is some sample output. I'm seeing that even after False / False, the sound play restarts & am unsure why.
# If I continue holding button_B through one more play, the sound stops, as expected, and button_B.value is True
# but I had expected this to occur earlier when I held B through the first complete sound play.
# If you'd like to test with my sound, it's in the sasa-chairs folder at:
