Trigger MP3 Decoders

  • What has an spreadsheet got to do with coding an MP3 Player?
  • Some viewers might spot that the table of binary numbers on the right represents the decimal number on the left.
  • On the featured MP3 player .. it is possible to "trigger" the track by sending a pattern of bits to the MP3 player.



  • Each bit represents the High/Low status of a pin the board.  Of cours you can do this manually .. but heck .. why not use an Arduino to trigger the patterns!
  • This gives us a method for playing different sounds as the model/toy is touched!
