I am trying to build an alarm clock, I've got pretty much everything done except for the alarm itself. I need something to play sound files of a sd card, since I want to use custom .wav files. I am running the whole alarm of 5v from a micro-usb cable, so the speaker should run of that too. So:
- runs off 5v
- plays files from sd card Thats pretty much all I got, thanks for any help.
