The l293D motor is a 16-pin motor driver IC which can control the set of two or more DC motors simultaneously in any direction like forward or rivers.
If you don't interest to read watch the below video
L293D is designed to provide by directional drive current of up to 600mA at a voltage from 4.5V to 36 voltage. You can use it to control small DC motor toy motors.L293 motor driver also called AC H-bridge motor driver
Why Use L293D
Why we will be used this type of L293D driver if we know the output voltages of Arduino Uno pins are 5 volts like the input voltage is 12 volts. but the output pin like analog or digital pin output is only 5 volts so the 12V motor does not run these 5 volts so we will use this type of driver like l293D and also an L298N motor driver. In the l293D motor driver, we will be connecting for DC motors Like 12V Motors. This l293D motor driver we are placed directly on the Arduino Uno Board.
