Arduino Voice Recorder

  • Records a standard micro SD card with a capacity of up to 32 GB.

  • The recording is a WAV file using A-law compression so it can be replayed easily on PCs and other equipment.

  • Voice activation can be set so recording only takes place when there is sufficient volume. Recording will stop if the level is too low for more than 15 seconds.

  • Powered by a single 14500 size Lithium ion cell.
