You might be thinking why we need L298N for controlling a motor. The answer is very simple, Arduino board or a microcontroller IO pins don’t have enough current/voltage driving capability to drive a motor. … It can be used to rotate the motor in both directions and to control the speed of the motor using PWM technique.
Why do you need a motor driver?
Motor drivers acts as an interface between the motors and the control circuits. Motor require high amount of current whereas the controller circuit works on low current signals. So the function of motor drivers is to take a low-current control signal and then turn it into a higher-current signal that can drive a motor.
Why is a driver circuit needed between microcontroller and DC motor?
To overcome the problems in their interfacing, a motor Driver IC is connected between microcontroller and DC motor. Motor driver is a little current amplifier. It takes a low current signal and gives out a high current signal which can drive a motor. It can also control the direction of motor.
What is motor driver Arduino?
About. The L298N Motor Driver is a controller that uses an H-Bridge to easily control the direction and speed of up to 2 DC motors.
What is the difference between a motor driver and a motor controller?
‘ The TLDR is that a motor driver simply handles the power to drive the motors, whereas the logic and digital control has to be done by an external microcontroller or microprocessor, whereas a motor controller has all of the logic circuitry built in and can be controlled by a higher-level interface such as a PWM signal …

How do I choose a motor controller?
Choosing a Motor Controller
- The first consideration is the motor’s nominal voltage. …
- Once you have found a range of controllers that can power the motor with the appropriate voltage, the next consideration is the continuous current the controller will need to supply. …
- The Control method is another important consideration.

What is the use of H bridge in motor driver IC?
Generally, the H-bridge motor driver circuit is used to reverse the direction of the motor and also to break the motor. When the motor comes to a sudden stop, as the terminals of the motor are shorted. Or let the motor run free to a stop, when the motor is detached from the circuit.
What is an H bridge circuit?
From Wikipedia, the free encyclopedia. An H-bridge is an electronic circuit that switches the polarity of a voltage applied to a load. These circuits are often used in robotics and other applications to allow DC motors to run forwards or backwards.
What is a DC motor driver?
DC Motor Drives. Definition: The DC motor drive is a type of amplifier or power modulator that integrate between the controller and a DC motor. It takes the low current and then converts it into a high current which is appropriate for the motor.
How do you program a motor driver?
Arduino Motor Control Setup
- Connect 5V and ground of the IC to 5V and ground of Arduino.
- Connect the motor to pins 2 and 3 of the IC.
- Connect IN1 of the IC to pin 8 of Arduino.
- Connect IN2 of the IC to pin 9 of Arduino.
- Connect EN1 of IC to pin 2 of Arduino.
- Connect SENS A pin of IC to the ground.
What is L298 motor driver?
INTRODUCTION. The L298 Driver is a high voltage, high current dual ful bridge driver designed to accept standard TTL logic levels and drive inductive loads such relays, solenoids, DC and stepping motors.

What are 3 types of motor controls?
There are four basic motor controller and drive types: AC, DC, servo, and stepper, each having an input power type modified to the desired output function to match with an application. From left to right, an AC servo motor, a DC brush-less motor, and a stepper motor.
How does motor controller work?
Simply put, a DC motor controller is any device that can manipulate the position, speed, or torque of a DC-powered motor. … Also, unlike some AC motors, DC motors are easily reversed by simply switching their leads so that the DC current runs in the opposite direction.
