I'm trying to figure out how to wire and program a non joystick device for controlling the robot. I'm not sure how many switches we would use, though it will probably be 3 or 4, depending on what exactly we use for/on our arm. Does any know if I need to take any special considerations when deciding where to wire these on a serial port and what pins match up for the different controls on the ports? Any help is appriecated, and if a thread already exists for this, I can't find it, so point me there.
