- Let's see how to control a Stepper motor with an Analog Joystick using an UNO and the Easy Driver motor driver.
Check out our tutorials page at : brainy-bits.com/tutorials/ to get the schematic and more information on this tutorial. - วิทยาศาสตร์และเทคโนโลยี
The way you talk throught he code is so clear. I literally now understand it all. There ahs previously been so much I don't understand that it's all alin and I can't follow, but you talking through each bit made sense.. SOOOO good
So happy to find this the store and all the other sweet stuff on your page!!!! Subscribed!
Thanks for the Sub and for watching of course :)
Thanks for the video, you explain really well. I work on a project : an automated stockage cupboard. Basically, I have a similar X axis and a Y axis a little bit different built on the X one to allow 2D movements. These explanations may be really usefull for me since I learnt python but not arduino language. I may give you more info when I finish the project if you want to.
That is cool! I had some trouble following the code but thanks for the tutorial. Probably have to take a closer look.

I'm trying to format a code with a keyboard control for a six degree of freedom robot and this was invaluable to me so much clearer now thank you
Thank you for the comment, always great to see that the videos are helping others with their projects!
wow such a nice tutorial for me, it really helpful since I do not have any experience yet with that little guy (stepper motor), keep going to make a similar project,
Thanks for taking the time to comment Amir and thank you for watching!
It is incredibly rude to criticize someone's pronunciation of words when all they are doing is sharing information. Please stop it! No matter where you are or what language your native language is, there are going to be variations. I have a friend in England that claims he can drive 25 miles from his home and be unable to understand what anybody is saying. However, they would all claim to be speaking "English." If you are from the states, you should understand at least the notion of different dialects, although they are more spread out. Just watch television to understand what I mean.
If the presenter is not speaking their native language, but in yours, then they are making an exceptional effort to share their knowledge. The least you could do is respect that. Done with rant.
BTW, thank you, Brainy-Bits, for the video. Subscribed.
Greetings from Auckland NZ - TOTALLY AGREE WITH YOU.
Great project!
Thanks for the video, it would be really helpful if you could do a similar one to configure a stepper motor to use it with a controller
Thanks so much for the great video
Looks like a great way to build a camera slide for filming TH-cam videos. Hope to do that for a future project soon.
Funny you should ask, I've done one not too long ago :) You can check it out here: th-cam.com/video/WzrRIPhIiaU/w-d-xo.html Thanks for watching!
It is good that it has good 'hold current', my older controller did not have hold current and motor would be able to be pushed out of place when not moving.
Thanks so much! Is there an easy way to use a 6 wire stepper motor with this driver?
I wish you made a closer look to the driver. However, I appreciate your work. Thank you! :-)

Hi there Brainy-Bits, how much weight could that motor pull? Im looking for a motor to add motion to my camera slider. I would attach the belt to the camera carriage. Do you have a video where you show the assembly? thanks
On their website they have a NEMA 17 motor which is rated for a Holding Torque: 2600g/cm (37 oz/in) so the absolute max for a pully of diameter 20mm (approx 3/4") would be 2.6kg but effectively it would not be able to lift it, just hold it. For a horizontal slider it's more than enough and up to say 45 degree incline it should still be plenty assuming you're not adding lots in the way of friction from the slider.
I was looking something like this to control my front wheel of RC car to control with a joystick thanks a lot I will try to workout based on this.
But the problem is I have l293d motor shield not easy driver.
hi brainy nice work...i use your tutorial to custom my video slide,work fine! but I will like controll full steps of the motor and not back to the center position when i release the joistik.
If possible set the speed 'for moving from point A to point B to create time lapse using the joistik button.
how can I change your sketch?
Great demo video!
+12th Man Airplane Thanks for the comment and for watching!
awesome video! very informative
Thanks for watching! We have more tutorials using stepper motors on our TH-cam channel, you can check them out here: th-cam.com/channels/H2m9XX8jSyVMkZUXwETPTw.html
Thanks. Good tutourial.
Thanks for watching!
it is useful for me, thanks
Cool video shot, thanks for sharing, keep it up :)
Thank you for the video.
Thanks for watching Andre!
Great little project. When you used an analogue joystick I was hoping that the motor speed would be proportional to joystick position but as it is, the motor appears to move at a fixed speed - and control could be achieved with 2 spst switches(?)
+jayc2469 Did another video using limit switches, you can check it out on our channel here: th-cam.com/video/dQuTgngoFPQ/w-d-xo.html
Thanks for watching btw :)
Nice demonstration of a stepper motor, but your code can be smaller, Don't repeat yourself, functions!
Thank you for the help
thanks for your vid's , wondering how you would control 2 steppers with 1 joystick , X & Y
tks
My question is identical to the Muaathe Aziz; I would like a program with 2 limit switches, end on the left side and end on the right side (without joystick / Potentiometer) Thanks
Nice video.
It's cool,thank you for sharing it
Thanks for watching! Check out our TH-cam channel, we have many more tutorials using Stepper Motors:
th-cam.com/channels/H2m9XX8jSyVMkZUXwETPTw.html Also you can find more information about all of our tutorial at our website: brainy-bits.com/tutorials/
Can you save the last position when turning of the Arduino? So you can use that position as a reference next time you boot up.
hey...awesome tutorial...i want to ask that how to control the stepper motor by joystick using tb6600 motor driver. please make a tutorial on that also
Don't forget that I make tutorial pages for most of my tutorials here: brainy-bits.com/tutorials This particular one can be found here: brainy-bits.com/blogs/tutorials/stepper-motor-easy-driver
Thanks for watching!
I like your belt clip idea. Have you thought of adding a wing with holes for attaching things to belt.
The wing could be cut off if unneeded. What language is your code in?
That's a good idea about the wings, will check that out. The code is Arduino language based on C/C++. Thanks for watching!
Hi. I wish to use this on a car clutch, where the position of the potentiometer decides the position f the clutch pedal. Will it be able to hold the clutch weight in its position? Or does the programing needs any changes?
Thanks video awesome, but I have a big question, for control 16 servos we can use a pca9685, but the question is, how we can control 16 motor steppers individually? Exist a module for do this? Like a pca9685 for motor steppers? Thanks a a lot
Nice video;) I just subscribed
+Tech Insider Thanks for the Sub and for watching! :)
Hello. Can you help to write a sketch for Uno to control Nema17 (a4988) from ir remote. I need nema to do few step steps forward on 1 button, and same steps backward on another button.
Please, i will really appreciate if you can
Hola Brainy-Bits soy de Colombia, me gustaría saber si se puede flashear este código al arduino junto con el "grbl" para que funcionen de manera paralela, me refiero a usarlos al tiempo, si es posible me enseñas a compliar ambos codigos en un solo archivo. de antemano gracias.
tnx. can I use this for lifting a small weight attaching to the belt in the vertical position? I faced an alignment problem while am using a lead screw. please help me.
All the loops in this sketch assume that you are using full steps. If you change from full to half or a quarter steps these constants have to change and there in no provision to change them in the sketch.
16:10 for action
Thanks
Muy buen video, como se podría hacer para que al estar en el centro y un botón de la cerca se presione hacia un lado y vuelva solo a su posición y vuelva a presionar la misma cerca del botón hacia el otro lado y vuelva al centro pocicionar; Quiero decir que aga esa operación con solo presionar un botón gracias por todo
nice vid thanks, it would have been much simpler to fit limit switches!
would this also be possible by using a press button, telling it to go to position X and then once released go back ?
I love the video you made. What would the code and hardware setup be like for a second stepper motor to make a joystick controlled drawing machine/ cnc ...?

+Rien Wijnsma Got this question a couple of time :) We will make a tutorial video soon on using multiple stepper motors. Thanks for the suggestion and for watching!
+Brainy-Bits
Nice video, you have my subscription! Do you already know when you will upload the video using multiple steppers? I really need it!! :)
+horstdieblume2 I should have that one coming in a week or two. Thanks for the Sub, and for watching of course :)
Hi Brainy-Bits, this is a wonderful tutorial!! Thanks a lot.
Let's say i would like to control 2 or 3 stepper motors simultaneously, each motor needs to reach different angle(preset).
For an e.g. all motors are in home position, when the joystick is moved towards left/right, all three motors have to start move towards their preset position/angle.
Is that possible?
Will you do a tutorial related to it or have any links that will lead to my objective?
Thank you!!
got a reply?
trying to do the same
Can i run 12v directly to 12v motor though this joystick and skip the controller since DC motor control means varying the voltage? The potentiometers do just that.
Can we make a simple Linear Servo using this concept, but to read the signal from an RC receiver, instead of the joystick ?
Great
So where will you use this mechanism?
can you make a tutorial with l298n motor driver module?
can you please tell me where you got thoughs moters
👍 good job
Thanks for watching!
Great project. I have a question, is it possible to make this project without an arduino, that meaning that we could only use common electrical components such as resistor, ic (not an arduino tho), capacitors, and things like that. I'm just curious because of that is possible, it would really really hard to get, right? Hope your reply mate. Thanks again!
+Germán Diego Guisasola Plejo Well everything is possible :) Of course using a microcontroller like the Arduino makes things a LOT easier... it's possible to do this using discrete components, but couldn't help you on that one :) Thanks for watching!
can use a touch lcd screen to move the motor?. not the analog joystick
Hello,
I'm trying to build router table with automatic adjustment for router height and automatic fence position... I want to use 2 nema 23 stepper motor . my system needs is
1) auto-stand system (work without PC)
2) switch for choosing between x or y axis
3) switch for choosing resolution (1x,10x,100x)
4) MPG handwheel for fine adjustment (100 pulses per revolution) one handwheel for both axis, depending on the switch x or y .
5) 2 buttons for each motor for fast adjustment .. can I use arduino for this project ?
Hi, what does Latch/Auto means on a stepper motor driver ? I couldn't notice any differences.
so cool man
Hi there,
Thanks for a great tutorial. I am brand new to Arduino but loving the things I have learnt so far. Huge potential for these little products.
I have a project where I want to motorize a machine in the workshop which I use to cut finger joints.
I will use a stepper motor, easydriver, arduino uno, LCD keypad shield and a button as my hardware.
I want to set it up so each time I press the button the motor will move a certain amount (I want this to be adjustable through the keypad shield) and when I long hold the button it will return back to start. I know this is simple code for many people but I would love your help with this. It would save me much headache.
Please assist.
Thanks in advance
I've done something similar, you can check it out here:

Hope that helps and thank you for watching!
Brainy-Bits Hi
Many many thanks and sorry for the late response. I will study those details and get back to you.
Very exciting projects :)
can you please tell me about stepper Logic Voltage? current per phase? continuous current per phase? and Operating voltage?
I have some Micro stepper motors, Could I use an Arduino without a driver to control it?
Very cool.thank you share this projet.
+Ernando Franco You are welcome! Thanks for watching!
Can you program the arduino so you don't have to hold the joystick in position - instead so that nudging the joystick in one direction causes it to displace, and releasing the joystick does not make it return to its original position. cheers
Can it be used for horizontal position?
what stepper motor you used ?
Any way to do away with the 1025 thing and just leave the belt where it is when the joystick is let go? I just can't wrap my head around this code.
very good...............
Would this be possible using the Arduino Uno R3, GRBL CNC Shield and DRV8825 driver? How?
Where is your store link do you ship to middle east?
Very nice! How is the pulley on the left side(the one that is not connected to the stepper motor) mounted on the black plate? Is it a screw? Can you please take a close picture for me? Thanks!
+Ronneil Camara We print and sell those pulleys in our store here: brainy-bits.com/shop/new/gt2-idler-pulley/
We have 2 models, one with bearing and the other without. Both are mounted using a 4mm screw with nut to the mounting plate. Hope that helps and thanks for watching!
Awesome! Now I know where to buy them. Thanks a lot! :)
How much millimeters is the acrylic? Which power laser do you use to cut acrylic?
The one showed in this video is 3mm thick. We use a 80W laser, but we can cut much thicker than that if we wanted. Thanks for watching btw.
thanks
Thanks for watching.
Thanks so much, can you please do the same with rc controller
please please, I can not figure out how to change the length( i am missing info in vid?) I have tried looking it up to no avail. I also seem to need to change it going from 0 to full as it wont go up only down due to the weight on my cart, but its so lite
What did you use to join the two belt end together? Any link to this "fastener" ??
Here it is: brainy-bits.com/products/gt2-belt-clip
Thanks for watching!
can you write into the code for the stepper motor to spin freely when it is not moving?
Do you know how you would do this exact thing but pushing something with a lot more weight on the belt? I'm trying create a motorized slide-out bed for a van conversion so it has to push a fair amount of weight. Can you use a belt with notches or might you use a chain like a bike? I'm new to this and to Arduino so I have no idea how something like this is normally done. Thanks.
+Ben Falk Hi, in my opinion a Linear Actuator might be better suited for this application. Since you would probably need a lot of pushing force, no pun intended :). And a simple switch would make the linear actuator go in our out, but of course you could also control it using an Arduino and a relay if you wanted to. You can look here for an example of some actuators models: www.servocity.com/html/180_lbs__thrust_linear_actuato.html#.Vk3_89-rRE4
Hope this helps, thanks for watching!
+Ben Falk
A linear screw would work for this but would probably be too expensive.
A belt drive system will work and be more economical have less maintenance and will be easier to home engineer/design.
Lead screws will eat them selves if not properly square and level.
For a belt drive system you will have to have some rails/bearings for the load to ride on and let the belt do the in and out work. You wont have issues if your belt and rails are properly sized of course.
I have designed and installed factory automation systems with thousands of pounds of machinery moving in and out on bent drive systems.
There are limitations in everything so it is a bit hard to recommend a positioner w/o knowing more about speeds and acceleration deceleration curves but from what I can imagine from your description it probably will move pretty slow and will not have a problem with a belt drive system.
Ebay is your friend as there are some extreme savings on automation components. I have seen $10,000 actuators go for $200 you need to keep an eye out for overstock automation goods.
Search for something like linear rail or linear slide.
Here is a 6.5 foot rail set for decent price. You load would ride on this and the belt would pull it along.

Good luck.
not sure if this has been asked. I'd like to control an xy gantry setup with this type of control. could it be done with this setup?
+Chris Villareale Hi Chris, you sure could do that! Check out our other video which uses limits switches to limit the travel of the steppers: th-cam.com/video/dQuTgngoFPQ/w-d-xo.html
Thanks for watching!
Whats the alternative for Easy Driver for a laser cutter project ? I need to drive X and Y axis, a laser diode and two limit trigger (i guess). So any recommendations ?
+M. Yıldırım The stepper you will be using will indicate which controller to use. Voltage and specially current draw of the motors. Easy Driver is good for small stepper, there's also the Big Driver that can handle more current, if using very beefy motors that requires a lot of torque and draw a lot of current then you need to find a controller with specs that will match the steppers. Hope it helps! Thanks for watching!
a video WITH limit switches would be cool
Do you have a link to the 3d printed parts and other parts like the belt and pulley sprocket?
Thanks
+zerocool60544 You can find those parts in our store at: brainy-bits.com/robotics/
Thanks for Watching!
what if you wanted to control multiple stepper motors? could someone be able to control 8 or 12 with a single Arduino? perhaps with Mega?
How much is the system cost? I need some think like that but to be controlled not by joystick but already programmed for specific distance
+Muaathe Aziz That's funny because our next tutorial will be doing just that! Anyway you can check the prices for the parts on our tutorial page here: brainy-bits.com/tutorials/stepper-motor-easy-driver/
The tutorial should be available at the beginning of this week if you are interested :) Thanks for watching!
+Brainy-Bits even I also need something like this, but controlled for some specific distance, and after travelling specified distance, it stops right there; instead of coming back to the origin. Any tutorial?
Would be happy to know about it! :)
+Dhawal Panchal You can check out these prior tutorials here: th-cam.com/video/OR5cOzmLVuY/w-d-xo.html and here: th-cam.com/video/b_bA5Ha_mec/w-d-xo.html one uses tact switches to set and move the stepper to a position, and the other uses a keypad and LCD to enter travel distance. Hope that helps and thaks for watching!
How would i write the code if I didn't have an endpoint? I just want to use a joystick to make the stepper go either direction without any stops.
Does anyone know how one can wire an analog setup with real-time stepper motor control with easing? I. E. If the joystick is pressed a little bit it goes slow and then accelerates depending how much further you press it. Cool video Btw.
How would I adapt this to use servos as drive wheels for a rover?
Servo is a poor choice for a drive wheel, you need a DC motor ideally, servos are more for light duty functions I.e. rc car has a dc motor to run wheels and a servo to turn non drive wheels
I need to do the same, but with drivers l293 or l298 ... who helps me?
How would you do this using a DRV8825 driver?
I would like to use a motor (DC or Stepper) to turn a platter display, so that I can rotate the object around. I can do this, but the motor jerks to a start, and I can't figure out how to make it a really really soft start. Any suggestions ?
I'm completing a new tutorial that will be using 2 stepper motors, the tutorial should be out this coming Monday. It will have acceleration and speed control. Stay tuned...
I have one 5-phase oriental Stepper motor (PK596BW-N25) which is attached to the drilling machine .Currently this motor speed is controlled by computer program but for some practical reasons I need to control its speed manually by knobs or button . Is it possible ? Do you have any circuit for that.
+sameer kharadkar Hard to say, but if it's a standard stepper motor, you could probably connect it to a motor controller (EasyDriver, BigDriver, etc...) and control it with buttons, rotary encoder all connected to an Arduino. Thanks for watching!
Hello what would be the code if I used an L298N driver?
If I print out a treaty on my laser printer, does that make it a treaty printer?
LOL!
No...but the convention for all of this automation was hammered out in the "3D of Versailles"
Too bad the treaty is so one sided that in 20 years, those who imposed it will have to answer to the "3D Reich'
Can this work with the a4988 stepper motor driver?
ur website is not working. it would be useful if you can name parts or link where to buy them in video description. I want to know where to buy motor driver
thanks.
+jean-pierre Duchemin You're welcome :) Thanks for watching!
Can I replace the ease driver with a a4988?
why did you not include the input pin from analog joystick? or use the map function ?
+jai Lopez They are many ways to do the same thing, I just chose to do it this way in this tutorial, but if I was to do it again it would probably be different! Using the map function would have been great also! thanks for the comment and for watching!
it is seem that the joystick is control only the direction and no also the speed, am I right?
Thanks. Good stuff. Hey do you have the code in its entirety for me and my study buddy to stare at in full?
Check out our tutorials page at : brainy-bits.com/tutorials/ to get the schematic and more information on most of our tutorials. Thanks for watching!
Thanks. I did, and we found actually another project we're going to work on. brainy-bits.com/tutorials/stepper-motor-with-joystick-and-limit-switches/
Suggestion: some type of notification to show which parts you have in your store in stock so we can decide which set of parts to buy so we can begin work on a project. THANKS!
