I want to connect my garage door to a doggie door. Garage door up, doggie door locked and doggies confined to back yard. Garage door down, doggie door unlocked and doggies are free to pass into the garage for shelter.
So...I will need a switch actuated by the garage door and a solenoid(s) controlling the latch on the doggie door.
The question is, what is the best circuit to fire the solenoid(s), one time, and then shut off until the door changes position? I do not want to leave them energized for hours at a time.
Any help appreciated!
TIA
