Physical buttons


#1

Hello All,
I want to make some physical buttons like emergency stop, Go home, preheat.
Is there a way for me to send signals electronically to Pi to trigger those commands on Octoprint?
If it is a complicated subject to explain if you can just point me towards the solution with key search words I can study myself.
Thank you
