• SOUND

  Received a few parts in the mail today, namely:

  • Mini Audio Magnet Raspberry Pi and Arduino Speaker 3 Watt 8 Ohm JST - PH2.0 Interface Balance Connect Rectangle Passive Horn Trumpet Loudspeaker
  • MakerFocus 2pcs I2C OLED Display Module 0.91 Inch I2C SSD1306 OLED Display Module Blue I2C OLED Screen Driver DC 3.3V~5V for Arduino
  • Dfplayer Mini,MP3 Player Module For Arduino UNO Modulo Musica Audio Voice Board Shield TF Card U Disk

  Had trouble driving the MP3 player from the Feather M0, so I swapped in an Arduino Uno, and things went much smoother. And bonus - because the new OLEDs are also I2C SSD1306, just like the Feather OLED, I could reuse all the display code.
  

  And with some example MP3s, we have SOUND!

  Stuffing it into a cardboard tube to see about size and packaging.

  Not too bad.

  Going with a FeatherWing OLED for displaying feedback to the operator. The screen is displaying in white text on a black background what would be selected when the top is depressed, and changes to black text on a white background when actually depressed.
