# Frequent question: How does l298n control DC motor speed?

Contents

## Can L298N control speed?

One of the easiest and inexpensive way to control DC motors is to interface L298N Motor Driver with Arduino. It can control both speed and spinning direction of two DC motors. And as a bonus, it can even control a bipolar stepper motor like NEMA 17.

## How does a speed of a DC motor is controlled?

Thus, the speed of a DC motor can be controlled in three ways: By varying the supply voltage. By varying the flux, and by varying the current through the field winding. By varying the armature voltage, and by varying the armature resistance.

## How does Arduino L298N control DC motors?

Plug one motor into the terminal labelled OUT1 and OUT2. Plug the second motor into the terminal labelled OUT3 and OUT4: 2.) The row of pins on the bottom right of the L298N control the speed and direction of the motors.

## How do you control the speed of a DC motor using esp32?

To control the direction the DC motor is spinning you use the input 1 and input 2 pins; Apply LOW to input 1 and HIGH to input 2 to spin the motor forward. Apply power the other way around to make it spin backwards; To control the speed of the DC motor, you use a PWM signal on the enable pin.

## How does the L298N work?

The L298N is a dual H-Bridge motor driver which allows speed and direction control of two DC motors at the same time. The module can drive DC motors that have voltages between 5 and 35V, with a peak current up to 2A.

## How do you use motor driver L298N?

Using the L298N if straightforward. If you want the left motor to rotate in one direction, apply a high pulse to IN1 and a low pulse to IN2. To reverse the direction, reverse the pulses to IN1 and IN2. The same applies to the right motor.

## How do you control the speed of a DC shunt motor?

Speed Control of DC Shunt Motor by Armature

By varying the value of R we can vary the voltage across the armature. Because speed N is directly proportional to armature voltage, it is possible to change the speed by changing the value of rheostat R.

## How do you slow down DC motor speed?

Most DC motors can be slowed down by reducing the supply level of power, Volts, lower volts and resulting less amps, will create less electrical field and will slow motor down. For more gradual speed control there are electronic solutions that are called PWM (Pulse Width Modulation) controllers or Mosfet H bridges.

## How does Arduino increase the speed of a DC motor?

IN1 pin of the L298 IC is connected to pin 8 of the Arduino while IN2 is connected to pin 9. These two digital pins of Arduino control the direction of the motor. The EN A pin of IC is connected to the PWM pin 2 of Arduino. This will control the speed of the motor.

## How does Arduino control DC motor speed?

DC Motor Speed Control Circuit Diagram

Connect 5 volts pin of the Arduino with the 5 volts pin of the L298n motor driver module and one side pin of the 10K ohm potentiometer. Attach the GND pin of the Arduino with the GND pin of the L298n module and another side pin of the 10K potentiometer.

## How does L293D control motor speed?

To control the speed of the motor :

1. The speed is set by using an analogWrite to the enable pin.
2. Speed of the motor can be changed by changing the value in “analogWrite”, The motor spins at a maximum speed if the value in analogWrite is set as 255.

## How do you connect 4 motors to L298n?

Connect the Arduino Digital Pins to the L298n Module see our example diagram below, in the diagram we have 4 and 2 DC motors so digital pins D9 D8, D7 and D6 will be connected to IN1, IN2, IN3, and IN4. Then connect Digital 10 to module pin PWM 1 you need to remove the jumper fist plug Digital 5 to module PWM 2.
