Hey, not sure if this is the right approach, I am trying to build a cuircut that basically opens a door when a button is pushed, leave it open for a period of time, and then close it until the button is pushed again. I really have no idea how to get this to work. Any tutorials or suggestions as to what gate combinations i need to make this work?
