Hi, Brainy Bits, I am so sad that you are under rated tutorials mentor, all your explanation are precise, simple and easy to grasp and implement. I hope one day see a 10000000 sub. please don't let us down. thank you
Friend. Thanks a lot. I had been searching a lot to get rid of my analog potentiometer floating reads and this will save my life (hope so). I don’t need speed, but precision, keep simple and also portable. Thank you very much and will buy the encoder right now.
Hi guys, thanks a lot for that code and all. I´m looking for exactly that for hundred years and you made it happen. I´m very glad about it. I use it for my model train to move the track in front of an engine shed. Thank you so so much and continue with your great job. Stay safe. Many greetings from Germany.
this looks like a very useful setup, thanks for taking the time to upload, could you please add homing and limit switch's to the code, or a video on how to include homing and limit switch's, I'm new to motors and struggling with homing and limit switch's, i need exactly your setup in this video, same motor setup/encoder, i identical but with homing and limit switch's , ive been working on it for a very long time and about to give up, any help please. thanks
Hi! Great tutorials,everything well explained,without rushes. Ive seen all your videos, but i was (still am) looking for a multi movements of the steppers,previously saved in arduino code. This to avoid to use browsers, i.e., tell the arduino (by a string or similar) to move the stepper like this: move to 1stop,move to 2stop,move to 3stop etc. So,instead of using the encoder or a pot, to use sequencial predefined positions. Thanks!
I use your code but when I turn one side it works well but in the other direction it starts to shock and does not turn around nicely. can you help me why he does so? I use a nano ivp the big arduino. the project is now taking to long hahah im working on it for 4years now and still not making progress. gr buas
Nice, thanks. I think I followed all the steps but my stepper turns always in the same direction no matter which way I turn the encoder. Where am I wrong?
Sorry, cannot find this tutorial (nor subsequent ones relating to this first one) at that link. Is it under a different name or has it been removed. I would like to get involved more with my uno and stepper motors.
plz reply me.... Thanks for making this video .......I have some questions regarding my project are.... 1. for NEMA 23 motor 2.8 amp which driver should I use 2.plz can you send Arduino coading for ' if we rotate rotary encoder 30° then motor rotate 15° in opposite direction ' 3. when I rotate encoder the torque is same as on motor specifications or less?? Thank you very much.........
Hi, thanks so much for the tutorial. I have a problem where my stepper will turn fine in one direction but in the other it is unreliable and will twitch around. This is the same with this tutorial and the one for the NEMA stepper. I have tested both motors with test code and they are both good. I think it must be the encoder but I have 5 and they all act the same. Any ideas?! Thanks again.
I set this up, but on mine it doesn't always turn the stepper, and the lights on the driver board kind of switch around without input, I must have messed something up in the code.
parabens Brainy exelente projeto teria como gravar as duas posições e depois fazer a leitura, e que ficasse repetindo a gravação? direita esquerda? abraço Brainy
Could you do that same setup, but use the encoder to "start the motor in 1 direction, having it just run continually, until you push the button to stop it, or reverse the encoder? Also, the further you turn the encoder, the faster the motor spins. So 50% encoder clockwise means motor spins at 50% speed continually in the same direction? Thanks.. Great Video
nice tutorial !!!!!!. Tell me something plz. In your video you can control the position of a stepper motor by rotating the rotary encoder. If you want continues rotation with speed control (like a potentiometer for example), can you do it with rotary encoder? . For example, you can control the position as you video. Fine. When click the rotary encoder, instead of returning back, can you use it for continues speed control ? (like a potentiometer?) thank you
is there is a possibility to remove the shock from the stepper motor. when turning the rotary encoder it is only one direction .if I turn one way, it goes well but in the other direction it is shocking and it does not go well. how can I solve this?
Hallo, I wanted to build an automatic grill for shashlik ... The mechanics are not a problem (and most of it is ready) but we were thinking about something that would turn it automatikly for example 1/4 turn every minute by pushing a button! But we have no clue how to program something like this...Has sombodey an idea?
Hi, I am controlling my stepper motor automatically from the Arduino board, but once it moves and stops where I want, It does not go back to original (home) location [after short delay]. Any help with coding please
Hi! Have this encoder a little snap for accuracy? like the one in the car audio system of the volume control. Sorry for my english. Greetings from italy.
Now just replace the cheap Rotary Encoder with a normal one that does not skip steps. Any way to make tutorial using buttons and a way to choose direction and number of steps to choose on LCD?
what if I wanna use more than 1 stepper motor?? lets say that for stepler motor one you have ints PinCLK, PinDT, PinSW... how would it be for then 2nd? could i name it PinCLk2, PonDT2, PinSW? and for each statement repeat twice but the second one adding 2 indicating stepper motor 2? Your answer would mean a lot.. Im new to stepper motors and Im using this stepper motors to control a robotic arm... thank you
How can i use this encoders in a robotic arm with those stepper motors and save the positions to after make an infinite loop ??Can you help me please ??
Hi,- Excellent tutorial. Can you tell me if the USB connection on the breadboard power supply is for 5v in or out because if its for 5v in I think you would need a special USB Cable. I will definitely get one if I can drive it from a USB input. Thanks - Keep up the good work
Hi, I believe these Breadboard power supply can be powered by USB, but keep in mind that a typical USB port on a computer has a 500mA limit. Or you could use a Cell Phone charger with the correct cable like you said. Thanks for your comment and for watching!
hey brainy bits ..please help me brother..i want to control two stepper motors exactly like that..can i control two stepper motos with one rotary encoder?i want to move the motors at same time..
+Rube G No, you would have to implement some sort of Home function when the Arduino starts up, to make sure the stepper motor goes to a starting point. You can check out this video here where I talk about using limit switches : ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-dQuTgngoFPQ.html Hope that helps and thanks for watching!
Hello. Very interesting video. Sorry to ask a boring question, but where do you get the gear from? I'm having trouble finding anything on Ebay/Amazon and can't seem to find it in your store?
+DarkShadow753 I cut this little gear at the last minute for this video with our laser cutter. We will start offering more custom parts in our store this coming year. Thanks for the comment and watching!
greats think it very important for a beginner ARDUINO UNO programer my questions : *1st :can we use an arduino to control a real industrial machine (using a PC power supply to supply the Arduino ) ? *2ed : what happen when we use Arduino in an electromagnetic interferance place ......are there risques of loss informations controlling ? best regards frome Nouari LAZREG automation Engineer and Operation manager of AFITEX company
It depends on what kind of industrial machine ( control signals required etc ) . A pc power supply has both 12V and 5V so you have the answer. A Engineer who ask "what could happen in a electromagnetic interferences" ...you a Engineer, aren't you !? Man you're askind for the "shielding"...
AMIGO COMO EU FARIA PARA USAR 2 MOTORES NESSE MESMO PROJETO ? E PARABÉNS PELO VÍDEO. FRIEND LIKE I DO TO USE 2 ENGINES IN THE SAME PROJECT ? CONGRATULATIONS AND VIDEO.
+Brainy-Bits I would like to control 3 stepper motors with different "rotary encoders" modules for each of them, and I would appreciate if you can explain me a doubt that I have, the encoder can be connect to different pins, for example I have a Arduino mega and I would like to know if I can connect to pins 24, 25 and 26, I have read the pinout of Arduino uno and I realize that the pins to which you connect the encoder in the video has something peculiar as to the type of outputs as of digital inputs (pwm pin) thank you very much
+Billy Zamora Díaz Check out this other video we did here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-O9Pr1ZLYUmE.html were I explain how to make any pin an interrupt pin so you can attach 3 Rotary encoders to an UNO board if you want, each having their own interrupt! Hope it helps! Thanks for watching!
Is there a particular Arduino kit I should get to run a stepper motor like in this video? Amazon has several different brands I'm not sure what the differences are to choose one : (
I got the elegoo kit which had 5 motors and 5 drivers. The driver board in this kit does nothing but increase the voltage from the arduino pins, and the leds on the side of driver show which pins (connected to motor) are getting power (which is great for learning). "Elegoo 5 sets 28BYJ-48 ULN2003 5V Stepper Motor + ULN2003 Driver Board for Arduino"
Can u help me? I know how to use an enconder and a stepper but, i want to learn how to save a sequence of movements with variations of speed during 5+ minutes and use a button to repeat the actions that ive done before...
The idea is a motion control... I want to use 5 motors with encoders to enter different sequences of movements, cw ccw, speed variations... Saving the movements to repeat forward and backward. Can u do a video about it? Tks!
Thanks for the suggestion, I have though of doing something like this, recording movements and play them back... Will try to do a video on that. Thanks for watching!
Can I use this setup to run a 12v stepper motor? Also is there a safer way of ensuring the rotary encoder doesn't skip or twitch when it misses the que?
+jason daysh Check out our other video here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-O9Pr1ZLYUmE.html i made some changes to the interrupt for the rotary encoder to make it more precise. Not perfect of course but better :) Hope it helps. Thanks for watching!
I got this motor in a starter kit from sunfounder. They say, that i can use the 5v pin of the arduino, but the kit is really poorly made and i think, the guys from sunfounder just don't know, what they are doing. Their example code is also shit. I don't have a power supply, so what should i do?
Hi Mike, you can find a tutorial page for most of our videos on our website here: brainy-bits.com/tutorials including a pic showing all the connections. Hope that helps and thanks for watching!
+sidgarth ansac You can check here: brainy-bits.com/tutorials/ to find more information, parts used and a schematic for most of the tutorials we post on RU-vid. Thanks for watching!
nice work, but i think if you connected the knob to a pulley by a cable and turn it you will get the same result, I m just joking thank you for your work.
How did you manage to spin it that fast? It is 4096 step in one revolution according to spec (www.instructables.com/ORIG/FQY/RHST/HMVJ7U24/FQYRHSTHMVJ7U24.pdf) and frequency 100Hz.. which makes it about 40 seconds for one revolution, that is how fast I managed to spin it.. thanks.
From my understanding the library we are using runs those steppers in 4-step sequence. Your mention of 4096 steps per revolution is correct when the stepper is run in 8-step sequence. So in 8-step it will take 4096 steps for a full revolution of the shaft. But in 4-steps it will only take 2048 steps. That's why the stepper is running faster in this tutorial video. You can checkout our tutorial page here: brainy-bits.com/tutorials/stepper-motor-rotary-encoder-p1/ and get more information. Hope that helps and thank you for watching!

I was planing to the same project (without the push button turing tha same previous position) , but i notice than the driver lights stay always turned on. This mean than the motor is always on! and consume a lot of battery . how you can obviate this problem ?
+Julis Lybeshari The module that comes with this Stepper motor, doesn't have a pin to put to sleep or turn it off, but I guess you could use a 5V relay to turn it off with the Arduino when it's not needed, that way it wouldn't consume any power. Hope that helps and thank you for your comment and watching :)
