Arduino and 2-wire actuator (power door lock)?

Haha, I know what you mean. But my kids are still too young. I don't like them disconnecting the electric fence to open the coop door.

I've seen the prefab door openers. I have a door on a hinge now, and I have all the mechanical pieces put together to open the door when the latch is pulled (it is currently set up with a modified sprinkler timer to dump some water in a bucket... total rube goldberg device. It worked good, except when it is < 32 degrees F outside, which was last night).

I'm also wiring in a real time clock and will get it set up so that it opens a little after sunrise, depending on the date.

Thanks!
