| At an industrial facility,
there are two ventilation hoods. Ductwork connects both hoods together
with an upside down Y. At the top of the ductwork is one blower that
sucks air up out of both hoods at the same time. At each hood is a
switch that's used to turn the blower motor on. If someone working at
either hood flips their switch, the blower should go on, providing the
blower motor hasn't overheated. The blower motor has a temperature
switch that opens if the blower gets too hot. Use three toggle switches, one light, and a 12 volt power supply to simulate this setup on a breadboard. |
