Currently working on automating valves using a raspberry pi and have done this easily for a few other projects. My issue is my new project needs to control more valves than there are GPIO pins on a pi 3. Does anyone have a good tutorial on how to use a pi zero as a USB gadget so I can use those GPIO pins for the rest of the valves. Networking them together won't work here because of the strict wifi at the university so I'd like to do this just via USB.
