I am brand new to PCB designing (started yesterday) and am doing it as a fun little side project. My goal is to produce a working PCB that has a very basic function. My problem is this:
I have no idea how to make wires (I think called a net in EAGLE) "cross" without connecting to each other. I was thinking of having little soldering hole type things either side of the wire (the one that is part of the PCB), and soldering another wire to them to jump over the other wire inside the PCB (hopefully, that made sense), but I would have to have 100 holes and 50 wires for this project.
I was wondering if there is a much more efficient way of doing this? I have heard the term "Air Wires" thrown around a lot but I do not know if this is what I need, as well as double-sided PCBs. At the moment I am using a single-sided PCB but that can change
Edit: Sorry I am bad with terminology for things like this. I have tried to make it more clear but please point out any mistakes I have made or if you need any clarification.
