Bend all audio files to your will with the Adafruit Music Maker shield for Arduino! This powerful shield features the VS1053, an encoding/decoding (codec) chip that can decode a wide variety of audio formats such as MP3, AAC, Ogg Vorbis, WMA, MIDI, FLAC, WAV (PCM and ADPCM). It can also be used to record audio in both PCM (WAV) and compressed Ogg Vorbis. You can do all sorts of stuff with the audio as well such as adjusting bass, treble, and volume digitally.
All this functionality is implemented in a lightweight SPI interface so that any Arduino can play audio from an SD card. There's also a special MIDI mode that you can boot the chip into that will read 'classic' 31250Kbaud MIDI data from an Arduino pin and act like a synth/drum machine - there are dozens of built-in drum and sample effects! But the chip is a pain to solder and needs a lot of extras. That's why we spun up the best shield, which is perfect for use with any Arduino Uno, Leonardo, or Mega.
We believe this is the best MP3 playing shield you can get, and at a great price too. Here are some specs:
Features the VS1053B codec chip - decoding Ogg Vorbis, MP3/MP2/MP1, MP4, AAC, WMA, FLAC, WAV/PCM, and MIDI. Encodes Ogg or WAV/PCM
Stereo audio out with proper audio filter caps and ground reference so it can be safely connected directly to headphones, a stereo system or other powered speakers
7 extra GPIOs that can be written or read through the Arduino Library for reading buttons or lighting LEDs
MicroSD card socket, for any FAT16/FAT32 formatted SD card from 64Mb or greater.
Full 3.3/5V level shifting for SD and MP3 chipsets
Built-in MIDI synth/drum machine with dozens of instruments
Plenty of optional breakouts for pins like the card-detect and microphone input
Each order comes with one fully assembled and tested shield, 2 2-pin terminal blocks, a stick of 0.1" male header and a 2 x 3 female header for the ICSP connection. Some light soldering is required to attach the through-hole headers to the PCB for plugging into the Arduino as well as the terminal blocks for the speakers. Speakers, headphones, an SD card and Arduino are NOT included!
We're wrapping up the full tutorial with photos of the shield, but for now, we have a detailed tutorial with lots of information about the VS1053 as well as instructions for how to use our Arduino library that will get you playing sound effects in under 30 minutes.
Revision History
As of Aug 28, 2024 - we've updated this PCB with Adafruit Pinguin to make a lovely and legible silkscreen. We've also updated the music maker to use the 2x3 SPI header instead of pins 11/12/13 and the terminal blocks now come pre-soldered on.
