Hi Guys, In this post, I will demonstrate how you can run or control 6 wired unipolar stepper motor with Arduino using L298N driver module. The unipolar stepper motor has six wired but L298N driver module has two connectors either side to connect only four wire, I will show you how you can connect and run unipolar stepper motor with L298N driver.
What is L298N driver module
Arduino is running on 5 volts and it’s current output only 500mAmp, so run any dc motor direct with Arduino, not a good idea. Here is the motor driver comes, L298N driver module works on 6 volts to 35 volts and maximum current output is 2Amp. You can run either one stepper motor or two dc motors with this driver module.

Arduino code for stepper motor and L298N driver module
#include
const int stepsPerRevolution = 200;
Stepper myStepper(stepsPerRevolution, 8, 9, 10, 11);
void setup() {
myStepper.setSpeed(50);
Serial.begin(9600);
void loop() {
// step one for one direction:
Serial.println("clockwise");
myStepper.step(stepsPerRevolution);
delay(400);
// step one for other direction:
Serial.println("counterclockwise");
myStepper.step(-stepsPerRevolution);
delay(400);
}
Wow I had no idea I could use an L298N as a stepper driver. Just a few fixes to your code example and it ran great!
#include
const int stepsPerRevolution = 200;
Stepper myStepper(stepsPerRevolution, 8, 9, 10, 11);
void setup() {
myStepper.setSpeed(50);
Serial.begin(9600);
}
void loop() {
// step one for one direction:
Serial.println(“clockwise”);
myStepper.step(stepsPerRevolution);
delay(400);
// step one for other direction:
Serial.println(“counterclockwise”);
myStepper.step(-stepsPerRevolution);
delay(400);
}
Perfectly working ok!
Thanks so much for sharing! I have tried with 12V 1A power supply. Also as a next step I gonna make a transistor array with 2SD1711 (which seems to be obsolete and very less expensive these days) So we can easily handle that power and heating problem.
Also see below the data sheets for the motor I have used 23KM-C057

All the best!

Very good example now your video motivate me to buy aurdino . Can you please tell me is it possible that if I want to rotate stepper motor to specific angle ?
360 degree = 200 steps
It is unfortunate that the L298n does not have any current control like the A4988 or other Pololu boards used in 3d printers. Some external circuitry is needed to limit the current. I will try the circuit I found here: bristolwatch.com/ele3/2a.htm
not working #include what is the next library we have to use ??
#include
Can I use the Mks Osc Stepper Motor Driving Controller Pulse Pwm Speed Reversing Cont T8J1
with the Arduino Uno and with my stepper motor Nema 23?
thanks,
Does this code work with the Arduino Uno?
