How to generate an interrupt from an analog signal

Doug,

Maybe it was just me, but I let the smoke out a couple of Op Amps when I was starting off. Remember most Op Amps are cheap so get some Op Amps and breadboard some of these circuits up and if you let some smoke out just think of the loss as a very low cost tuition. The main thing is to get in and do something as that is where the learning starts.
