stealthrt Posted April 19, 2023 Report Share Posted April 19, 2023 Hey all I have a project I am needing to do but I'm unsure as to the best way to go about doing it. What I am wanting to do is check to see if a tablet or laptop is plugged into the USB-c cable so that I can have a visual representation of confirmation that it is connected correctly. Most of the tablets I am using do not have any visible feature that showcases that its plugged in or not. But even if it did i would never be able to see it due to the tablets being close together. This is what my setup I created looks like: When your placing the tablet/laptop into the slots from the front it's difficult to tell if it made it into the connector or missed it. So my idea was to create a PCB that has 6 female USB-C inputs and 6 female USB-C outputs. But I am not sure what I need to test on the pins to determine if its connected to something or not? I plan on using an arduino to check the voltage and see if it drops XX amount 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: Quote Link to comment Share on other sites More sharing options...
