i accidentally alternate connect ground and 5v with water flow sensor
and it happen to output nothing at all after that,
is it possible that it now has a permanent problem?
it does not show output using this sample code: http://diyhacking.com/projects/FlowMeterDIY.ino
it does work well the first time i tried it, but yea...
is there anything i can do to make it work again? or another sample code is there one?
