This is some excellent support. As I go though my pile of stuff to do I can count on these short classes to get me on my feet. I've have been learning from cheap modules, and most of the times they come with no explanation, This helps a lot. Thanks
Excellent!
Thank you!... you do a fantastic job communicating the details ... and are very good at explaining functions methods and reasons!
You are welcome. I am glad found it useful. Here the Learn Arduino in 30 Minutes (video): robojax.com/L/?id=135 video . And here is my Arduino Course at Udemy.com with 100s of projects from beginner to Advance bit.ly/rj-udemy
Thanks this is fantastic mate, really helped me a lot with my project :) great work!
Proud to see an Iranian with such a knowledge
Thank you. Very helpful!!!
Thank you. I particularly enjoyed your explanation of the use of the Arduino library. I also appreciate the access to your software. It is early days for me but if I am able to make use of it I will let you know in a more practical way. Robert from Brisbane Australia
You are welcome Robert. I am pleased that you found my tutorials useful. Ahmad from Canada.
Thanks so much for this, nice and detailed and allowed me to get it working first time. Subscribed.
Awesome, thank you!
very good tutorial thankyou. Happy to subscribe
You are welcome.
is this the same for a 5 wire stepper motor? what do i do with the centre tap to coil end wire. do i also have to write this in the program? thanks
Thanks for the video! I have an Nema 17 hooked up to a L298n and an Arduino. I have no issues operating it, but I'm having problems powering it. If I use a 5v 1a supply, it works but torque is low. If I use a 12v 2a supply, the torque is great, but the L298n pulses ever second or so which sends power to the motor. It doesnt appear to actually turn the motor, but it makes a buzzing noise which is VERY annoying. Do you know why I'm getting this pulsing from the driver?
Great man!! Just one thing can i use other digital pwm pins apart from 8910 11
Thank you for your tutorial, it was very helpful, and very clear !
You are welcome. I am pleased that you found it useful.
Hi Jax. I found you by accident but I'm glad you did. You have the only video with enough information for me ( a noob ) to understand. I was wondering if you could make a video or explain to me how to code the stepper motor to pulse once everyday. Thank you so much for the amazing video!
Aka What would be the value of the RPM and and the SetSpeed in order for the stepper motor to turn one rpm per day.
Hi, I am pleased it helped. to use time, we need to use clock module here is the video th-cam.com/video/7hBtXdoaAOY/w-d-xo.html which has alarm. now when alarm is triggered you can do anything you want. From this video which I used push buttons th-cam.com/video/csf_G1pi0ps/w-d-xo.html learn more about speed control. and use clock module to trigger it at exact time. Good luck and stay safe. Please subscribe.
@@robojax THANK YOU SO MUCH!!!
the rpm depends on how large each step is. smaller and more precise steps will take shorter time to complete one revocation and larger steps will take very shorter time to complete one revocation.
Hello, I wonder what's the array of 6 yellow jumpers on the Hex pcb are for.
Thanks for the prompt reply from Canada Ahmad. The internet is a wonderful addition to our lives as it creates hands across the sea.
I am an octogenarian and have recently started to learn to write Arduino software. My hobby is making electromagnetic clocks which I design myself. What I trying to find out is if it is possible to use Arduino as an alternative to Mach 3(Wizard) because I have put a couple of steppers onto a small metal lathe and need some software to drive them. It is not something I have done before. I got close to getting Wizard to run but my parallel port computer died and getting Mach 3 to run from a USB is possible but more complicated.

You are welcome. Learning is journey that never ends. Good luck with your project. snag.gy/AHhRpV.jpg
How to connect the scanner engine to play hired music like on the floppotron TH-cam channel?
That’s Great, Thank You for your help. I have a question, can the stepper be made to go in one direction and then reverse to other direction without buttons and more than one revolution? I need the stepper to go
50 revolutions.
you may learn from this video. The same code will work. just pay attention to wiring in your module th-cam.com/video/csf_G1pi0ps/w-d-xo.html
This is awesome
Thank you.
Hi great video, the most detailed i have ever seen but you didn't give the schematics for the wiring??
So how is the motor current monitored and controlled at the constant rated current value. for any motor??
what will happen if i connect the 12v dc power supply to the 5v pin in L298 IC?
whether it sends 12 v to all the 4 output pins or burns out?
I would have to check the module. But according to datasheet it can handle up to 46V robojax.com/download/datasheet/robojax_L298_motordriver.pdf
This is awesome context Ahmad! Well explained for a newbie like me. can I use nodemcu instead of arduino? What would I do differently if I can use nodemcu
Yes it will work. Just power the module end define pins, it will work. Make sure to use proper PWM pins and define them in esp 8266
Hello, I would like to ask a question. When I set my motor speed to 60, my motor will not spin, when I set the speed to 300, it can rotate normally. What should I do to make the motor turn at speed 60 or low speed? My motor model is 42BYGH47. Thank you for taking the time to read my question
THANK YOU
you are welcome.
Hi, firstly, I really appreciate your videos. Second, my question is that why isn't the motor getting a full rotation i.e 200 steps or 360 degrees in the first example?
Hi, Thank you for your comment. Could you type the time like 2:30 or something so I click and watch. Hard for me to watch all video. I have got over 300 videos and forgot what is what.
@@robojax Thanks for replying. I was referring to 14:00 i.e the first example.
The code shows you are giving a step of 200 to the stepper... this means a full 360 rotation. but the video shows only a rotation of like 60 degree and then the direction of rotation switches.
@@robojax I would like to see sequence changed to - rotate CW then power off - then power on then rotate CCW, please show how to code it...thanks
I have a project in That I have to control the speed of the stepper motor with the response output of load cell plz suggest some idea to combine load cell and the stepper motor.
is the output of load cell a voltage? if so then it would be like controlling it with potentiometer.
Please also upload video on ! How to make cnc using arduino and stepper motors
have not worked with CNC but I will look at it.
Is there a drawing of connections between motor/L298/Arduino for a 28byj-48 stepper motor?
I have tones of 28BYJ-489 videos. just search my channel.
Thanks so much ROBOJAX, the only problem is why is my driver getting overheated ?
Hello, there are two ways to stop the motor. one is hold which consumes energy and holds and the other is just stops the signal and power to the motor. I think I have used it in this video th-cam.com/video/csf_G1pi0ps/w-d-xo.html and may be in this video th-cam.com/video/cYTICj4DWYc/w-d-xo.html
Please make a tutorial on push button servo control
I will try to make your requested video soon.
Hi, I just uploaded a video on how to control servo motor with push buttons th-cam.com/video/7woqNH_qby4/w-d-xo.html
Robojax omg ur so honest !!! I have never seen a man like u , informing of what we requested ! Thank you so much !!!!! Thank u once again!!!!!!
Keep such good videos coming! ! All the best 👏👏👏👏👏
You are welcome. Thank you for your request. I just updated the link.
Hello sir, I need run the stepper motor 25 revolution clockwise and take rest and want to run 25 revolution ccwise and take rest. Can you help me? I have Arduino Uno and My motor 24 volt. Drive I can buy L298N. Pls help me for the full code in Arduino
can this project connected via hc-05 bluetooth? if yes, can i know how the connection is
Yes it can be needs some work. i would have to make video for that. I am not sure when . But I just add it to my "to do" list.
hi..
can you make video controll motor stepper with ULN2003 to rotate 90 degree and back again please,thankyou
Watch my other video that might help. th-cam.com/video/Sl2mzXfTwCs/w-d-xo.html
I will have another video on how to control precise position of motor.
@@robojax oke i will watch thanks
What is the reason for connecting the ground to both the power supply ground and the Arduino ground. Isn’t ground just ground? Isn’t it risky to send a say 6V power circuit back to the Arduino ground? Sorry for questions, I am still only learning.
it is a good question. we have circuit. electronics go (by convention) from + terminal to - terminal. if we use 1 wire, electrons can't complete the circuit. if we have just signal wires to Arduino, the circuit is not completed and it wont' work. it is the same if we san connect 1 wire (the positive wire ) from battery to a bulb and expect it to work.
@@robojax Thank you, that makes perfect sense.. it's not like a water flow where we are just getting water to the destination. We need to complete the loop. Got it. Thanks for putting this tutorial out there to help others.
thanks in advance....could i connect a joystick to do this
you did not say to do what. but here is the joystick video th-cam.com/video/6N8Iq353GM8/w-d-xo.html and you can use the values from joystick to heave a meaning to be used by the stepper
hello sir
12VDC with 2amp current is sufficient for driver or not ????? OR i have to connect 12VDC/4amp power supply for driver.. because driver current rating is 2amp/channel it means 4amp total current.... what should i do??
the voltage doesn't matter as you can go up to 24V. But the current is determined by your motor. if you motor need 0.1A then just a little higher or if your motor is 2A then have 2.5A power. So it depends on your motor.
@@robojax thankyou sir
what would be maximum rpm at 12v power supply?
Depends on the specs of the motor. Read your motor datasheet.
Nice vid. Using more or less the same setup, but my L298N is getting very hot. You get burned! Is this normal?
12v power supply. Nema 17 motor(smallest)
No. it is not normal. You must be connecting the wiring incorrectly and it causes the energy to be wasted in the wiring. Check the wiring.
Hi, i have the same problem. Did you found a solution?
Not really. My wireing seems correct. Might be the motor pulling to much current-have not checked. Ordered a more robust driver.
@@ingmarkranefeld6442 Basically I think my motor is pulling more than 2Amp, and this driver is good for max 2amp.
Yes I already figured it out. My nema 17 uses 3.9a and the max current ist 2a. Already switched to another motor driver. Thanks for your answer.
I want use NEMA 23 stepper motor 19kg what are the required parts
that number has on meaning unless you get the datasheet, see the voltage and current requirement of the motor. For example in this datasheet www.cui.com/product/resource/nema23-amt112s.pdf you will see this item has multiple models and model NEMA23-17-15PD-AMT112S has phase current of 4.2A and operating voltage of 5V. so you pick a motor driver that can handle that current. you will search for "stepper motor driver 10A 5V" or "stepper motor 8A 5V" you must select current 20% or higher than the required current.
has anyone gotten this L298N+Nema 17 to work with ESPHome or Tasmota? if so, could you please show the wiring diagram as well as the codes?
I am not sure if it worth it to make such project. I wish there was a way to aks people to see if 1000s of poeple need it as sometimes I spent 2 or 3 days on a project with very complex functionality and I epreiment to fix it; but when I post it in a month 2000 people won't watch it and that is depressing. so I have given up. Most user don't even spare their free click on "subscribe" button. I belive TH-cam is failing because I am not getting back in return. Instead if I work on lowerst paid job I will make more monmey than TH-cam viddeo. Simple subscription from user is stamp of approval on a channel and that channel will get more views, but people act as if they deserve to get free tutorial and dont' even bother to subscribe wich costs them nothing.
HI! is this full step control? I want cotroll half step and micro step, please help me. Thanks
Hi, this is full step control. Half step can be done as well. Check library and my other videos.
@@robojax how about micro step?
you need different motor driver. you have a look at this article www.printfriendly.com/p/g/uJsyne
Hallo . Can we make a stepper motor with motor knob sketch ?? Is it possible to work ? With the motor of your video ?
did you check the code? I spend hours making it. check the page again.
Robojax I check it but as I see it’s for one step at time / revolution/ speed control ... I ask for the first example in arduino code motor knob . Thanks for the reply . Welcome for the comment
You missed it. It was just bellow that. Again you didn't go further in the page. I have removed the code now to prepare it for a course.
Robojax ok thanks for the patient . I am waiting for the code
valo
An easy way to find windings. connect a pair of wires, if the rotor becomes harder to rotate, that is a pair.
Thanks
Thanks for sharing.
Thanks a lot for this great tutorial but I’ve done the same steps and my ic got so hot can any one tell me what’s the problem pls
is the motor rotating or it is stall? make sure you connect the voltage that is rated for the motor. I assume you haven't changed the code.
@@robojax yes its rotating smoothly and ive used the same code but the l298n ic gets really hot even that im using 12v power supply with the nema17 motor
Something is wrong. either voltage rating of motor or wiring. Try to change the order of wiring for poles of motor. I can't think of anything else.
@@robojax I wanted to chime in with a similar issue. Everything runs smoothly but like Saad Free said, the heatsink specifically is beyond hot to the touch. I know it's a heatsink but it seems a little excessive. Wanted to ask if yours gets to that temperature? I changed the wires for one of the windings which only caused it to change rotational direction but still become extremely hot.
@@bpm009 Were you able to solve the problem? I have the same issue
Sir one help for our mini project how control this setup with humidity sensor and crystal display plese give coding and wiring sir please sir
you posted the same question twice. I can see them all in one page. please see my reply to your comment under other video.
How can speed control code be combined with direction control code ??
When I explain the code, I never leave a single line without explaining. So if you watch the video without skipping, and pay attention. or watch it twice or 3 time, you can learn how it works. Then you can combine them.
@@robojax I have already seen it twice.
But the connection between them, does not need specific codes ??
yes. that is what I said. Watch them and learn it. You can do it . watch both videos. here are my stepper related videos th-cam.com/channels/kcBSig_Iu4ZnAIeCeG1TVg.htmlsearch?query=stepper
we followed everything but wont work. need some help there is data sent in the driver as shown in the led but the motor didnt start
It has to work. 1000s of people used it and it worked. Your wiring must be wrong. You have put your wiring in correct way. Do you hear any sound from motor? Have you supplied external power to the motor? Arduino can't run this motor.
is it safe to use l298n for nema17
this motor is nema17. Yes it is.
@@robojax you mentioned something about heat sinck
if the current exceeds 2A, then you need to have extra heat sink. otherwise this should be good. By the way it shows you have not subscribed. Spare a subscribe click. I have spend over 5 hours on this project. You need to spend 5 seconds to click on "Subscribe"
@@robojax i did
i want add potential for this code
#include
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");
myStepper.step(-stepsPerRevolution);
delay(500);
}
The cooler heats up too fast, what could be the problem?
either over loaded or when it stops it consumes. There are two types motor stop. hold and brake. look at other videos for stepper on my channel. here is how to Find Specific TH-cam Video in a channel bit.ly/findTH-camVideo
Gracias por tu cooperacion prro :v

Hi Ahmad ! I own the same kind of L298N board but mine has jumper connecting EN pins (to idk what). I am not sure what is the diagram of this setup so i cant described more than this :/ My question is, do you think in my case, it is a necessity to connect the EN1 and EN2 to arduino the way you did it, and if not, is the 5V GND wire from the L298N to the arduino still necessary ?
Here is a picture : ae01.alicdn.com/kf/HTB1FKVOSpXXXXX_aFXXq6xXFXXXS.jpg
Thank you very much ;)
Hi, Here my video on the other module of L298N th-cam.com/video/cYTICj4DWYc/w-d-xo.html
ol is openline and not overload
I first checked the datasheet and did not find OL, then . I had to download the video and watch it to see where I have mentioned the OL. Thank you for correcting me.
