Ok before I read your post this is what I found out. The button seems to be pulling the pin to ground even when the button is not pushed. I unhooked the wire and jsut touched the wires together and it rings and when I hook the button back up it rings once. I am not sure why this happens. I am guessing maybe it is the light in the button. Maybe if I buy one that is not lighted the voltage will stay at 3.3 V but just my thoughts for now.
