Sparkfun MP3 Player Shield
Offers a 3.5 mm audio out jack
0.1-inch spaced header for speaker out
Features a microSD card slot
The Sparkfun MP3 Player Shield is an MP3 decoder with the capabilities of storing music files onto a run-of-the-mill microSD card, thus giving you the ability to add music or sound effects to any project. With this board you can pull MP3 files from a microSD card and play them using only one shield, effectively turning any Arduino into a fully functional stand-alone MP3 player.
The MP3 Shield utilizes the VS1053B MP3 audio decoder IC to decode audio files. The VS1053 is also capable of decoding Ogg Vorbis/MP3/AAC/WMA/MIDI audio and encoding IMA ADPCM and user-loadable Ogg Vorbis.
The VS1053 receives its input bitstream through a serial input bus (SPI). After the stream has been decoded by the IC, the audio is sent out to both a 3.5 mm stereo headphone jack, as well as a 2-pin 0.1-inch pitch header.
This shield comes populated with all components as shown in the images and schematic, but it does not come with headers installed.
Le bouclier est bon, le lien de documentation doit être mis à jour
J'ai eu ça pour le son d'un projet de robot. J'ai eu une expérience frustrante en essayant d'utiliser l'exemple dans le lien de documentation. Les bibliothèques utilisées par les exemples ont changé et ne sont plus compatibles. Robot Shop : veuillez mettre à jour le lien. Une fois que j'ai trouvé la documentation Sparkfun mise à jour sur https://learn.sparkfun.com/tutorials/mp3-player-shield-hookup-guide-v15?_ga=2.91878362.1511680999.1640800548-620763291.1637437471 et des bibliothèques et un exemple de code sur https://github .com/madsci1016/Sparkfun-MP3-Player-Shield-Arduino-Library, j'ai pu le faire fonctionner, et cela fonctionne bien. J'utilisais des haut-parleurs externes (une petite "barre de son" pour un ordinateur portable), j'ai donc dû dessouder et ressouder les cavaliers SJ3, SJ4 et SJ5 pour éviter un bourdonnement désagréable. Après, le son était bon. Un problème que j'ai eu était lorsque j'ai branché un bouton à la broche 10 (qui devrait être libre), l'arduino se bloque lorsque la broche 10 est connectée à la terre. Je ne sais pas de quoi il s'agissait, mais j'ai fini par en utiliser une pour les broches A (broche numérique 15) à la place et cela a résolu mon problème. Commentaire RobotShop : Merci, Ian. Nous avons mis à jour la description du produit et les documents utiles.

Shield is good, documentation link needs to be updated
I got this for sound for a robot project. I had a frustrating experience trying to use the example in the documentation link. The libraries used by the examples have changed and are no longer compatible. Robot Shop: please update the link. Once I found the updated Sparkfun documentation at https://learn.sparkfun.com/tutorials/mp3-player-shield-hookup-guide-v15?_ga=2.91878362.1511680999.1640800548-620763291.1637437471 and libraries and example code at https://github.com/madsci1016/Sparkfun-MP3-Player-Shield-Arduino-Library, I was able to get it to work, and it does work well. I was using external speakers (a small "sound bar" for a laptop), so I needed to unsolder and re-solder the jumpers SJ3, SJ4 and SJ5 to avoid a nasty buzzing. After that, the sound was good. One problem I had was when I hooked up a button to pin 10 (which should be free), the arduino would hang when pin 10 was connected to ground. I don't know what that was about, but ended up using one for the A pins (digital pin 15) instead and it solved my problem. Comment RobotShop: Thank you, Ian. We updated the product description and useful documents.

Nifty sound output shield.
Audio quality was absolutely excellent with more than enough control over sound characteristics for my needs. Only small disappointment is the lack of mounting holes, otherwise 5/5. Great service from Robotshop as well.

Bouclier de sortie sonore Nifty.
La qualité audio était absolument excellente avec un contrôle suffisant sur les caractéristiques sonores pour mes besoins. Seule petite déception est le manque de trous de montage, sinon 5/5. Excellent service de Robotshop également.
