L 293 Motor Driver
A motor driver is an integrated circuit chip which is usually used to control motors in autonomous robots.Motor driver act as an interface between Arduino and the motors.The most commonly used motor driver IC’s are from the L293 series such as L293D, L293NE, etc.These ICs are designed to control 2 DC motors simultaneously. L293D consist of two H-bridge.H-bridge is the simplest circuit for controlling a low current rated motor.We will be referring the motor driver IC as L293D only. L293D has 16 pins.
The L293D is a 16 pin IC, with eight pins, on each side, dedicated to the controlling of a motor. There are 2 INPUT pins, 2 OUTPUT pins and 1 ENABLE pin for each motor. L293D consist of two H-bridge. H-bridge is the simplest circuit for controlling a low current rated motor.
