The problem is I have a speaker and an microphone mounted on my robo. I've decided to go non-wireless for this project, but I don't want 3 wires running from the robot to the computer (speaker,microphone, and other robot stuff). Is there some way to combine all there wires in to one? My idea is: create a custom cable that has usb and 2 aux connectors combined into one connector, and make the wires split when it reaches the computer. Is there a better way to accomplish this?
