L293D driving Bipolar stepper
The following circuit diagram is for
bipolar stepper motor. But connections remains same
for unipolar except connecting common of the unipolar
motor to +V(Pin8 of L293D). The logic voltage (pin16) given +5V and
to enable pins(1,9). But all
these circuits have problems because we had to generate sequence
using any other circuit. In order to avoid circuits to generate
sequence,we use a sequence generator IC L297 with
L298 to drive motor
