< Mentor Note -- thread moved to HH from the technical engineering forums, so no HH Template is shown > Hello! My partners and I are trying to create a alarm that is set to go off at a certain time then is turned off by pouring water on a water or moisture sensor. We have a few ideas but they seem much to complicated or to expensive to test out. Another problem we are facing is how to reset the alarm without the excess water from the previous "trial pour" automatically turning off the alarm, instead of manually drying off the sensor in order to try again. We plan on incorporating Bluetooth into our final project design as well, but we don't plan on getting their for a while if we even do. Thanks!
