the attached diagram is used to control dc motor direction of rotation. if the two
potentiometer is equal in value the motor will stop rotating.
My problem is this, if the pots values is below 80% say pot 1=70 and pot 2=70. i expect at this value that the motor should not rotate, but the motor still rotate in both forward and reverse direction.
Please, anybody with better circuit or who have an ideal on how i can make the two ics ua741 not to give output when the two pots values is the same.
Thanks for your prompt responses
