Re: Vex Spike relay module?

Just to make sure this is clear: Spike Relays will not be able to switch fast enough to act like a normal speed controller. You should not try to do that. The switch in spikes are actually physical switches which take time to change. Constantly switching causes a strain that it can't keep up with. And even if that wern't true, is most cases in your code, loops only run every 20ms, which is much too slow to act as a PWM speed controller.
