Here is am experiment you can try at home. Turn off your robot - and remove the leads from the PWM that go to a motor. An arm or wheel that you can drive by hand
FP or van door - move the arm back and forth. Now short the leads together and try the same thing. Is it
easier or harder to move the motor?


Now you now how the brake/coast mode works on the Victors.

Second home experment - if you have some Lego motors,
connect two of them together - try spinning the shaft of one and watching the second. What happens? Can you
explain it?
