I think this will only work with CM, lights are powered by the RCX and this
will probably run the motors all the time. I guess a touch sensor in raw
mode would do it, but wouldn't return anything like 0 and 100. What happens
when a motor is stalled? Current goes up and voltage drops I suppose, now
how does that relate to a raw input?
