This is hopefully not going to be overly convoluted, or difficult, or or even impossible.
My wife is a chicken keeper, and we have a door that we must open in the morning to let the chickens out and close at night to let the chickens back in. This has to be done manually so we need to be home by nightfall each night to keep predators out.
I'm trying to design a system where my wife can control the door from her smartphone wherever she may be.
I have a small DC motor that that can do the job of raising and lettingl the door, and i know that I can reverse the direction of the motor by switching polarities.
I also have two outlets that are WiFi controlled. So my thought was to plug a DC converter into each WiFi plug and have them feed to the motor with opposite polarities. Of course I realize that we cannot have both on simultaneously but I need some way to ensure that when Outlet A (+/-) is powered up, the current doesn't flow back to outlet be which is off (-/+).
Is there a simple way to ensure that the two lines only feed the current one way, so when the other is on I don't get a backflow problem?
Or is there a simpler more elegant solution that I don't know about?
Thanks in advance for any advice for this truly ignorant newbie.
