To stop the motor hard you short its connections. A simple but not elegant way is to use a relay. Make sure the first transistor is off, then energize the relay. A more elegant solution would be to put a P channel FET or PNP transistor accross the motor: Q1 is used to turn on the motor as you have it now. faza fazan german safety razor
