Hope this is the right place to post this.
I am working on a project and am looking to see if it can be addressed with arduino. We have a factory that has something like 20 "stations", but we change the machines that go into each station depending on what we are making. I would like to have a button on each machine that can be pressed to capture output, with one press being one output.
Is there a way that we can use arduino where when we move the machine into the position, connect the button (Plug the connector in), and then capture the button press? Could this be achieved with 20 buttons, each button being unique, with 1 arduino?
