floppy bipolar stepper motor driver?
i wanted to salvage my old floppy drive , and take the small bipolar motor from it
after i removed it , i looked around and i found small ic ( LB1838M )
its data-sheet is here
i found somethings (pins configuration) in the data-sheet that i don't understand
like : IN1 , IN2 , ENA1 , ENA2
so , what this pins represent for ?
and , can i remove this ic from the board , and make a circuit like this one in the data-sheet and use it to control the stepper ( independently ) ?
if yes , i need to know how to make controlling buttons or something .
English in not my 1st language btw , so ...
thank you :)
