hello friends..
i am trying to control a unipolar stepper motor using ucn5804B driver chip and giving input for driver from an atmega32 microcontroller chip...
but it' s giving a problem....rather than normal rotation of motor i am getting a vibration in motor shaft ...it seems it is changing it's direction of motion very fast ..so not able to move in any direction.....
i have checked all connections and remade whole circuit many times ..
i tried with another piece of motor and driver chip too..but it is giving same response.....i am not able to understand anything ...
please help me if somebody knows what is the problem.....
thanks alot in advance......
