I would like to know how to make a button revert the signal it sent

[furrylilhamster]

For example, pressing a button once opens a door and pressing it again closes the door.

Welcome to the forums @furrylilhamster, also I would suggest using 2 buttons

Welcome to the forums @furrylilhamster!
I would recommend using 2 button that are the same size and then,
place one near the door and make it outside the structure.
then place another button also near the door but inside the structure this time.
then wire the button outside to whatever the door you are using like this:
when button pressed → open door
then with the inside button,
do this:
when button pressed → close door
Simple as that!
(Don’t forget to mark this as a solution if this helped!)
