Q:

How can I add a button for a garage door opener?

I have the following scheme for my garage door opener: 

and I want to add a push button to this.
Is it enough to connect a push button just as any other button: GND to scheme's GND and PB to the other pin of the button?

A:

Yes, You can simply connect an additional button between the PB and GND connections. Just make sure that all of the buttons used are momentary types that spring back to an open condition when not in use.
