: It actually can be done without code if you are using the speed controllers to control the motors you want to keep from backdriving. Just set the jumper on the speed controller(right under where the PWM cable plugs in) so that it is on the left two pins. This will put the speed controllers into dynamic braking mode, which will keep the motors from backdriving under weights equal to that of a robot. We almost thought our winch lift was in trouble last night, until I remembered that you could do this...

Nate, it turns out that our speed controllers had already been put into that mode and it sill backdrives. We have a 93 pound robot. CAN ANYONE PLEEEEASE HELP?
