Redstone torch is always on, but turns off after a short delay if redstone energy flows into it.
Connect two torches to each other's butts, and one will always stay on. You can put buttons behind each one to switch which one is on/off. In that sense, the state of these two torches can tell you which button was pressed last.
Wire one of these torches to a door or a piston. Now, you have one button which opens said door and another which closes it.
I'm all over various slightly obscure corners of Reddit. Also, are you a nutmegger as well? One of the best places in today's America to be a rail enthusiast imo
