I'm looking for help on a project my uncle asked me to work on. I have the general idea but cannot figure out the electrical side. Basically we are trying to make an "automatic opening and closing door". We want the door to slide open with a button press, and close with another button press. Basically, when the door slides open to the furthest position, the door would press the second button, starting the closing process. I also don't know how the door would know when to stop. So I guess is this even achievable? And would someone be able to help us? My uncle can sudo read schematics but we're both pretty new to this. Thank you to anyone willing to give it a shot!
