Hello everyone
Can any one please point me in the right direction... I'm a new hobbyist, and taking up electronics after many moons in absence.
I have a caravan, with only one ventilation hole. I wish to mount 2 small 12v PC fans with a set up to have one fan suck fresh air into the caravan for around 15 mins, then turn off, and then the other fan set to extract air from the caravan to the outside.
I know I can simply wire a 12v relay that when powered (using a 12v timer set on 15min increments) can start one of the fans, when the timer switches off the power to the relay, it would switch on the other fan...
What relay do I need?.. Im lost...
Many thanks for any help...
