                          The L293D is designed to provide bidirectional drive currents of up to 600-mA at voltages from 4.5 V to 36 V. Here we control two DC motors using L293D  quadruple high-current half-H drivers.

with PIC16F877A micro controller . working diagram of L293D is given below

                  To control the speed motor we generate PWM signal from PIC , The bidirectional control of motor by high and low state other digital signal from PIC, here we use inverting of duty of pwm when changing one direction to opposite direction for maintaing the speed of motor.
