No programming is required to get started but it will help to know binary. There are only a couple steps to set up your Little Soundie:

  • Connect to your computer using a micro-USB cable
  • Press the power/play button
  • Format the disk when prompted
  • Drag and drop your .ogg or .wav files

From here, audio playback is a matter of attaching a powered speaker and triggering the GPIO pins at 3.3V logic.
