Can anyone suggest where I might be able to get a mechanism for opening and closing a small door. The door will probably be about 12" square and can be hinged so that it swings like a full-sized door so the effort to open and close it should be quite small.
It needs to be secure against small animals (foxes etc.) when closed.
I want to operate it electrically so it can be opened and closed at set times (with a time clock from the mains) or possibly be driven by a photocell.
Searching for door opener only produces electronics for door latches and/or garage door openers.
