Using L298N Stepper Motor Driver To control 4 wires stepper motor Robojax.com

This is the Arduino code for L298N Stepper Motor Controller

In this video you will learn how to control a 4 wire stepper motor with L298N Stepper Motor Driver module. The code for 3 different Arduino sketch is also provided below.

Code for One Revolution

This code is make a motor rotate One revolution using L298N Motor driver . Watch video for the complete explanation. the amount of time delay you set, determines if the motor can complete ONE revolution or not.


  
/*
 Stepper Motor Control - one revolution

 This program drives a unipolar or bipolar stepper motor.
 The motor is attached to digital pins 8 - 11 of the Arduino.

 The motor should revolve one revolution in one direction, then
 one revolution in the other direction.

#include <Stepper.h>

const int stepsPerRevolution = 200;  // change this to fit the number of steps per revolution
// for your motor

// initialize the stepper library on pins 8 through 11:
Stepper myStepper(stepsPerRevolution, 8, 9, 10, 11);

void setup() {
  // set the speed at 60 rpm:
  myStepper.setSpeed(300);
  // initialize the serial port:
  Serial.begin(9600);
  // L298N for Robojax.com 
  pinMode(2,OUTPUT);// for EN1
  digitalWrite(2,HIGH);// enable EN1
  pinMode(3,OUTPUT);// for EN1
  digitalWrite(3,HIGH); // enable EN2
}

void loop() {
  // step one revolution  in one direction:
  Serial.println("clockwise");
  myStepper.step(stepsPerRevolution);
  delay(500);

// L298N for Robojax.com 
  // step one revolution in the other direction:
  Serial.println("counterclockwise");

Code for Rotating Stepper Motor One Step at a time

This code is make a motor rotate One step at a time using L298N Motor driver . Watch video for the complete explanation


  
/*
 Stepper Motor Control - one step at a time

 This program drives a unipolar or bipolar stepper motor.
 The motor is attached to digital pins 8 - 11 of the Arduino.

 The motor will step one step at a time, very slowly.  You can use this to
 test that you've got the four wires of your stepper wired to the correct
 pins. If wired correctly, all steps should be in the same direction.

 Use this also to count the number of steps per revolution of your motor,
 if you don't know it.  Then plug that number into the oneRevolution
 example to see if you got it right.

Code for controlling Stepper Motor with potentiometer

This code is control speed of a motor using L298N Motor driver with potentiometer in Arduino. Watch video for the complete explanation


  
/*
 Stepper Motor Control - speed control

 This program drives a unipolar or bipolar stepper motor.
 The motor is attached to digital pins 8 - 11 of the Arduino.
 A potentiometer is connected to analog input 0.

 The motor will rotate in a clockwise direction. The higher the potentiometer value,
 the faster the motor speed. Because setSpeed() sets the delay between steps,
 you may notice the motor is less responsive to changes in the sensor value at
 low speeds.
