Hi again everyone, thanks for all the ideas last time. For those who didnt read it, i am making a duck that quacks and flashes when it is placed on water. (GCSE Electronics). I have the water activated monostable working with a liquid sensor. Trouble is, it keeps going until the sensor is taken out of water (obviously, cause the switch stays closed) Is there any way of making it so that it needs to be taken out, then placed back in the water to make this work? Some kind of reverse latching thing? I know you guys were great help last time so thanks in advance again!
