I remixed the code to send a push notification after the sound passed a certain threshold. I switched from SMS because I didn't want to overload my SMS while debugging. It started a little too sensitive.
I also added a switch and status light so that I could control when it was publishing events. I added a "notifyLed" that would light up whenever an event published. This was primarily for debugging.
Is this a good/useful/informative piece of content to include in the project? Have your say!
