Datasheet

Microphones, by their nature, are very sensitive devices. They are prone to picking up all
sorts of noises (both electrical and acoustic) in addition to what you are trying to record. A
microphone circuit built on a breadboard is not likely to sound good at all. For good sound,
you will want to review the spec sheet recommendations and build this on a good quality
circuit board.
Recording Sketch:
Connect the Arduino to your computer with a USB cable and plug your headphones into the
headphone jack. Select File->Examples->Adafruit_VS1053_Codec->record_ogg to
load the example code.
Plug-Ins
The record_ogg example sketch demonstrates a powerful feature of the VS1053 breakout:
Plug-ins. OGG recording capability is not supported natively in the chip itself, but through a
plug-in code module. A binary file containing the code image of the plug-in is loaded from
the SD card at startup. Once loaded, the VS1053 becomes an OGG recording device.
To Record:
Press the start/stop button to start the recording. Press once again to stop. Each recording
will be stored in a separate .OGG file on the SD card.
To Playback:
Use any OGG capable audio player on your computer - or playback through the VS1053
using the Simple Audio Player configuration (see link at left).
