greathow:
My actual sensor is essentially two metal contacts hooked to 3.3v and ground. When I submerge the sensor in water, the voltage increases, but only slightly. I'd like to have an interrupt based on some threshold I set. Is this possible?
Is it really necessary to use an interrupt? if you were 5 or 6 (or 60) millisecs late detecting the presence of water would it matter?
