Do you want it light-level controlled or time controlled?

What sort of door do you want opened? Size? Weight?

 

We did this with a chicken coop a few months ago.

 

I have the perfect electronic circuit. I would 'set' it for a certain time and when it 'alarms' I would go and open the door. Then I would set if for another time(like sunset) and again, when it 'alarms' I would go and close the door.

Sometimes it's just to easy to resist.
