make a water sensor, which can be done by using a darlington pair and then make some metal very close together but no toching so when water is touching it so it formes a curcuit. then have darlington to activate the motors turning the shutters i hope this is what you want!
what is a darlington? Can u explain more abt the water sensor so i don't need a circuit board? also what is the function of the metal to form a circuit? any diagrams or examples?
An drigalirton is realy 2 transistors conected to geter to get a wery high gain (up to tens of thousents of hFE)
meby the schematic wod help
the switches detect wen the hatch has fuly open/closed and stop the motor.These are normaly closed switches (they conduct wen there is no force on them).there like ush to break switches
