Is the Digital Sidecar correctly powered? The 5V light needs to be shining bright in order for the inputs to work.

The 5V light was lighting up like it should be.

Everywhere I've looked says to connect ground to signal, so I'm not sure that is correct. Connecting the power to signal doesn't do anything either anyways.

We have other IO pins being used with encoders that are working perfectly fine. Whenever we try to use a limit switch on any of the pins, it doesn't work. I can try a new ribbon cable later today and see if that works.
