DC Motor Driver H-Bridge L293 (2 DC motors)
Build a DCwith H-Bridge technique can use IC L293D as in the article “DC Motor Driver H-Bridge L293 (2 Motor DC)” is. DC 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 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.
