Device that will run a motor in forward and reverse

If you put a Smart presents in your mail box how does it work?

I’m not sure I am following the thread title connection to the body…

But, you wouldn’t want to put a presence sensor in your mailbox. All that would do is tell you that your mailbox is present. That’s fine if you have a tendency to have your mailbox stolen, but, it won’t tell you when you get mail.

You’d want to use an open/close sensor like you’d put on a door or window.
