My dog howls when he's left alone. I want to build an alarm that will detect his howling, he's loud so it shouldn't be hard, and play back a couple of seconds of my voice. I'm guessing a electret mic and a recording module (my local radio shack has both, will do the trick, but I don't know how to connect it.
Does anyone know where I can find a project I can modify? Or even just a diagram?
