Regulating power to a servo with a relay

(since both of those will tell the FPGA to stop outputting a control signal to that device). Neither one is really an answer, but a workaround. I don't really see why you would need to make it stop, since you can't really smoke those little things (from what I've seen at least) and they don't output much power.

I think Servo::SetOffline() is intended to stop driving the servo (I've never used it). No need for a workaround

If you don't want this feature, why not use a regular positional servo?
