The Cheapest Stepper Motor And How You Use It (28BYJ-48 & ULN2003 Arduino Tutorial!) (WITH CODE!)

Do you have a 28BYJ-48 and a ULN2003 module that you would like to use? look no further! In this video I go over the basics and provide a bit of code for you to use to get started!

Here is the code:

Here are the physical specs:

Thank you for explaining that both the arduino and stepper motor can be powered from the same 5V external source. I'm an electronics noob, and I just went through like 5 other videos to try to find out how to power both devices, and strangely enough no other video creator bothered to mention the power supply for the arduino. So thank you for clarifying!

I've been looking for so fucking long, a single code that allows me to reverse the stepper direcction and the "crappy" one is the only one that worked, thank you so much

[luigipasta]

bro nothing is garbage, you are doing your best and that it's important.... keep moving forward!!!

This guy says he’s not a programmer the same way teachers say their not an artist when drawing, love the content 👌🏻

Half-steps and acceleration are fun to play with. You can get the thing spinning faster than it ordinary can, with acceleration control.
For 2 steppers, a ULN2803 has 8 outputs, so you can control two with 1 darlington array.

Awesomeness… love the way you printed out your code and explained.

I'm a newbie to all this, your video is brilliant! Explains a lot, understandable and clear! Thank you!!!

[peterknoll]

Nice video! I like the honest way of presentation.
Yes. For that task, I would go with "attachInterrupt" to change direction whenever a button is pressed.

Whatever happens in the main loop, the interrupt will execute. Even if the mainloop "stuck" in a delay function.
Interrupts always have precedence.

But as you mentioned: the code you shown is not perfect. I really like the honest way of your presentation.
Your focus was on the very basic operation of the stepper and the code.
Mission accomplished! 😊

Thank you for this tutorial. Simple, to the point, amazing job :D!

[falsillusion]

Thanks, I just wanted to find a way to make the motor constantly rotate, forever and your code was the easiest one !

[samwillard]

These motors are common in microwaves, but in a 120 V version. They are very strong. Thanks for the code! Just getting started on Arduinos. Great work, your imagination is very impressive!

5:10 So, if I need only it spinning on the lower speed in a constant motion, do I have to use an Arduino? All I need is it spinning in the lowest speed possible for my project. Other motors (DC motors) are way to loud and stepper motors are really quiet in comparison. Would it suffice only using the ULN2003 and the stepper motor? Maybe a turn on/off button maybe?

[wandersonsilva-fxcs]

I really enjoyed your class, congratulations! I have a question what is the maximum speed of this engine?

[astro_aviral]

How can i change the direction of the steeper Motor in the first example, I am making a star tracker but I want to reverse the direction of rotation 🙏🏼

[metallicaandchimaira]

For this motor do you HAVE to have it connected to an arduino? I have a motor speed control circuit and have it connected from the power to that. Then I am running the connections to the stepper motor board and it wont turn on :(

[floroubaldo]

Hello, Why my stepper.h library not working? I tried accelstepper and it work just fine.

[xrphobby]

How is it possible to rotate the motor 18degress each time the button is pressed? Thank you

[hydrolisk]

Thumbs up mate!!! Please expand your knowledge some more, you are doing a great job here. My suggestion on where to go next would be to learn about millis(). This is way better than using delays considering delays completely stop the code from running whilst a delay is in progress. Start with looking at the blink without delay code built in to the arduino IDE. This will help you later on when making more complex programs :P

[onizuka]

I have 2 of these motors and I want to control them using the Arduino uno and a gyroscope mpu6050, do I need an external power supply to power them or cable connected to the PC and 5v from Arduino should be fine ? Please answer

thanks, I'm going to use this for an automatic dog feeder
