Hi everyone,
I'm on a project where I have an arduino wich is connected to a router via an ethernet cable. But for redundancy reasons, I want to use a second (backup) cable either. So what I need is a circuit that switches between the main ethernet cable, and the bakup cable, when one of the arduino's pin is high or low. (The W5500 module is able to detect the link state, so that's how it will know when to switch to the other cable)
So I guess 8 relay would be the easiest way to do this, but they are loud and I don't want to use them if it's possible. There should be a way for this with some ic or something.
Made a little gif about it, where the perfboard is the thing i asked above.
Thanks for your answer / suggestion. Have a nice day.
