thank you boncuk,
it is ok servo motor for this?all supply is 5v?is this IC is 4 inputs?but 2 inputs only should be used?
 
you mean that, the h-bridge can control the forward , reverse and even stop?

just turn all for transistors off I can't see what all the hyp is over
 
Hi markjoseph,

the L293 can not only drive DC motors, but also unipolar stepper motors. Therefor it has four inputs. To drive a normal DC motor two inputs are good enough to have to motor rotate in either direction and also brake regardless of the rotation direction. (So only 1/2 of the IC is actually used)

Google for it to obtain the data sheet.

The L293 is no "exotic" part. So you should find it at any electronics shop with a medium assortment of ICs.

I made the schematic using ISIS out of PROTEUS.

Boncuk
