![]() ![]() The answer to this question is very simple that the Arduino or any other microcontrollercannot supply enough current to drive the motors so we need the separate circuit that drives the motor itself.A question arises that why do we need the Motor Driver in fact we can drive the motor by Arduino nano or any other microcontroller?.Why need the L298 Motor Driver? How to use L298n Motor Driver The enable pin of the motor driver IC that is the ENA and ENB enables the bridge inside the IC.Each input of the bridge lets the motor to rotate in either clockwise or counter-clockwise rotation. The circuit in the above figure is called the H-Bridge circuit and is used to control the direction of rotation of the motor. ![]() In order to understand the working of each bridge of the IC consider the following circuit: Let us learn about each bridge of the IC and its pins in some more detail.The above table describes the functionality of the pins of the L298 motor driver IC.The pinout of the chip is as shown in the following table:.Pin Configuration of the L298 Motor Driver IC The working of each of the pin will be discussed in the following section. As can be see that there are four input pins and four output pins along them two Enable pins are also available in chip.
