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.
