DC Motor with 8051

1) Motor.c

Here, L293D, DC Motor IC is interfaced with the microcontroller. There are 2 pins each for 2 motors can be connected to the output of this IC.

This IC is a direction control IC.

To explain what I have done in this code,
Look at the table given :

EN	MOTOR1	MOTOR2	FUNCTION
H	H	H	Go Forward
H	L	L	Opposite direction
H	H	L	Turn Left
H	L	H	Turn Right
L	-	-	Disabled

}
if(sw3==0)// right
{
