Click to expand... hi, Are you asking for a way for the motor to hold its position after stopping even when there is an external turning force being applied to the motor shaft.? How are you controlling the L293.? Last edited: Apr 2, 2010

magnatro New Member Apr 8, 2010 #6 you can brake the motor simply by making the inputs to the driver to the same logic???
