DC Motor Driver H-Bridge L293 (2 DC motors)

Build a DC motor driver with H-Bridge technique can use IC L293D as in the article “DC Motor Driver H-Bridge L293 (2 Motor DC)” is. DC motor driver L293D can be used to control the DC motor 2 pieces at once. DC Motor Driver L293D can be used to control a DC motor continuously or with a PWM technique. Dc motor driver circuit in the article “DC Motor Driver H-Bridge L293 (2 Motor DC)” only use IC L293D only. For more details see the following figure.

DC Motor Driver H-Bridge L293 (2 DC motors) Circuit

Working system of DC motor driver L293D is to provide control signals in the form of logic or pulse to the input lines 1A – 1B for DC motor control M1 and the input 2A – 2B for the control of DC motor M2 with the following conditions:

Input A   Input B   Motor DC

0                   0                   Motor Stoped
1                    0                   Motor rotates counterclockwise
0                   1                    Motor rotates clockwise
1                    1                    Motor Stoped

Note : Enable Input given a logic 1 to obtain such data in the table above.
