How do I use a l298n motor driver with Arduino?

How do I connect Arduino to motor driver?

Arduino Motor Control Setup

  1. Connect 5V and ground of the IC to 5V and ground of Arduino.
  2. Connect the motor to pins 2 and 3 of the IC.
  3. Connect IN1 of the IC to pin 8 of Arduino.
  4. Connect IN2 of the IC to pin 9 of Arduino.
  5. Connect EN1 of IC to pin 2 of Arduino.
  6. Connect SENS A pin of IC to the ground.

How do I power Arduino with L298N?

5V pin supplies power for the switching logic circuitry inside L298N IC. If the 5V-EN jumper is in place, this pin acts as an output and can be used to power up your Arduino. If the 5V-EN jumper is removed, you need to connect it to the 5V pin on Arduino. ENA pins are used to control speed of Motor A.

How do you control a motor driver?

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. IN1 and IN2 control the direction of the motor connected to OUT1 and OUT2.

How do you control the speed of a DC motor?

Thus, the speed of a DC motor can be controlled in three ways:

  1. By varying the supply voltage.
  2. By varying the flux, and by varying the current through the field winding.
  3. By varying the armature voltage, and by varying the armature resistance.

What is the difference between L293D and l298?

L293d contains a quadruple half-H driver meaning all the four input-output lines are independent. While L298N is a dual full-H driver meaning only the full drives can be used. … L293D is used for controlling motors rated at low current while L298N can be used for controlling high current motors also.

How do you program an Arduino?

Program An Arduino In A Few Simple Steps

  1. Arduino microcontrollers come in a variety of types. …
  2. To begin, you’ll need to install the Arduino Programmer, aka the integrated development environment (IDE).
  3. Connect your Arduino to the USB port of your computer. …
  4. Set the board type and the serial port in the Arduino Programmer.


How do you slow down an Arduino DC motor?

If you push the pedal down, you accelerate to full speed. If you tap the gas pedal, the engine accelerates and then slows down. If you tap it at a constant rate before it slows, you will maintain some of the momentum of the spinning motor and achieve an average (if somewhat jerky) speed.

What does an H bridge do?

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.

How does L298N control motor speed?

Control DC motors with the L298N

  1. If you send a HIGH signal to the enable 1 pin, motor A is ready to be controlled and at the maximum speed;
  2. If you send a LOW signal to the enable 1 pin, motor A turns off;
  3. If you send a PWM signal, you can control the speed of the motor. The motor speed is proportional to the duty cycle.

How do you control the speed of a DC motor using PWM Arduino?

DC Motor control using PWM Signals – Arduino

  1. Introduction. The DC motor speed in general is directly proportional to the supply voltage, so if reduce the voltage from 9 volts to 4.5 volts then our speed become half of what it originally had. …
