Here in this tutorial we gonna try to control a DC motor speed using a potentiometer, L298n Motor driver and an Arduino board, (we won't complicate things with directions or other functions). Before we learn how to control a DC motor with the Arduino, we need to understand some basic concepts of motor control. The L298N is a motor driver IC by ST Microelectronics. For driving the motor in both directions (clockwise and anti-clockwise) we need to use an H-Bridge. Very easy installation. It can control motors which operates between 5 to 35V and up to 2A. Specifications of L298N Motor Driver DC Motors Control Using Arduino PWM with L298N H-Bridge . It can control both speed and spinning direction of of any Bipolar stepper motor like NEMA 17. The L298N module can control up to four DC motors, or two DC motors with direction control and speed control because of its dual H-bridge circuit. 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. It is inexpensive and perfect for robotic projects. In this tutorial i'm going to show you how to control the speed and direction of two DC motors by the most common method PWM signals. For powering the L298N, I have used the 2 rechargeable batteries of 3.7V. Like in homes we rotate the knob at switch port to control the speed of roof fan. When I say control a DC Motor, I mean you can start a motor, stop it, make it rotate in forward direction, backward directions, increase the speed of rotation and also decrease the speed. By using electronic components we have made one project which called DC motor direction control using Arduino UNO board and L298 motor driver by using this user can revolve the motor to clock wise and anti-clock wise and using in different application. This module uses the PWM method to control the speed of DC motors. 2.) Don't forget to bookmark raspberry pi dc motor speed control l298n using Ctrl + D (PC) or Command + D (macos). When you want to drive DC motor with Arduino, you need some sort of motor driver module which can run motors and control the direction and speed of the motors. The L298 can control the speed and direction of DC motors and stepper motors, and can control two motors simultaneously. It is recommended to always use the external voltage supply. speed and direction of rotation using a combination of PWM Signal and L298N (H-Bridge). By controlling the motor, we mean controlling its speed and direction of rotation. great article sir than you so much.. PWM pin doesn't work for some reason. I was wondering how i would edit the code in order to use nrf24l01 module to send joystick data to other arduino with motors with the way the code works above?
