Well, long story short. I put together the little POC using my PIR sensor a while back. The shit deal, is that the sucker only writes high and low. Easy, for the win. Limited, for the loss.

I’m trying to do something with a dual speaker setup, in order to shine up my bugler alarm project. The code is boring…stay tuned…I might be able to come up with something amusing.
