I want to check if a tablet or laptop has a USB-C cable plugged in so I can have a visual confirmation that it is connected correctly.
Most of the tablets I use do not have any visible feature that shows if it's plugged in or not. But even if they did, I would never be able to see it because the tablets are close together.
This is what my setup looks like:
When you place the tablet/laptop into the slots from the front it's difficult to tell if it made it into the connector or missed it.
My idea is to create a PCB that has 6 female USB-C inputs and 6 female USB-C outputs.
I am not sure what I need to test on the pins to determine if it's connected to something or not. I plan to use an Arduino to check the voltage and see if it drops when something is plugged in, but again, there may be a better way of checking it.
My PCB would look similar to this one, but without the headers and holes and with more than one set:
UPDATE 1: So something like this?
