Between my second floor and attic there are stairs but at the top there's just a trap door in the ceiling. It's heavy enough that it's hard to open if I'm carrying a couple of things with one arm. I'd like to have some sensor on the stairs that triggers a motor to pull up the door. I'm assuming I'd use a stronger motor/winch like device which will wrap up a cable or rope connected to the door.
Is there an existing project out there that might get me started? It looks like the hardest part for me at this point would be knowing how to connect to an Arduino a winch-like device that would probably have to get it's main energy from a power outlet. Any step-by-step tutorials out there for doing something like that or any general recommendations on which materials I'd need, even?
Me and my son are new to the Arduino and don't have a great understanding of electricity, I'm afraid. Any guidance would be appreciated.
