28BYJ-48 stepper motor and ULN2003 Arduino (Quick tutorial for beginners)

A lot more information then what is in the datasheet. Thank you.

I cant wait. Just bought a beginner arduino kit. I have almost completed an internal security lock for a van on my 3d printer with wireless control. I work doing car keys and mechanics plus auto electrics. Im so excited to be able to make electro mechanical things. Solar panel raiser for sunshine passing. Remember that word sunshine 🌞

Thanks man. Made it easy to get started. Ur making the world smarter!

can you post the code for moving clockwise/anticlockwise, please!?

can we use the 28byj-48 stepper motor in replace for a dc motor? when I saw in the vid it looks impossible.

Please make a video on Circuit diagram of transister based controller used in printer.

Hinde me batao

Ладно, я понял что могу писать на русском языке )
Кстати , не плохой английский )

I increased the amps of my power supply and changed it to 3ms and it increased the torque so much.

you don't declared a ???

Strange behavior on mines...
Using half-stepping.
I use PORTB instead of the awfull digitalWrite...
Delay of 2 ms motor is turning ok.
Delay of 4 ms motor stays still ??? same for delayMicroseconds(4000).
Delay of 8 ms motor is turning ok again...

Servo motor not rotating but vibrating, why thats happening?

Could you big diagram

sorry noob question as I’m just starting to play with arduino.
Once you’ve programmed it with the arduino, you can disconnect the arduino and the stepper motor will be a standalone circuit ?

What software are you using?
I’m on a Apple Mac & I’ve found pololu tic but can’t find driver in usb so says not connected

How do you control 2 stepper motor I saw the datasheet there's a cw and acw on rd2 how about the other wheel if not the wheel will lock at one location I'm using mplab for pic18f4550 instead of arduino

That's work Nice

If you have two different types of stepper motor with different Steps can you use it in single project together like in cnc or 3d printer ?

pliz give code

while(1)
{
// body of the loop...
} // this can loop any code just put the code inside.

How to control it more precisely, so it just doesn’t spin but stays and moves as I order it?

can you post the codes?

How can I make the motor rotate slower?

Thanks

hey thanks for the video but i got a problem it gives me an error that says; "OneStep was not declared in this scope". what do i do? I checked the code 5 time to see if i did any mistake but no.

Hi can you please explain the conditions you wrote for the for loop in the void loop function, please reply urgently if possible

works great!!
but only rotates in one direction..

thx for making this vidio

Thank you so much it works without interrupting the other functions. love it from Philippines.

sketch_sep29a\sketch_sep29a.ino:1:27: fatal error: PIDController.h: No such file or directory that appears to me what is the solution please

does it work for arduino mega 2560 or just uno?

Excellent.

thanks for this , now im ready for the step motor project

I'm pretty sure you're not supposed to power the motor directly from your arduino

nice video. can i get a copy of the code. Thanks

i cant make it work, no lights on the driver/no movement

I have the same stepper motor. I connected it and wrote the code, but it only vibrates. No rotation.

hi, how much weight (kilos) can this motor lift?

Thank you for the video. the code pls!

Bro my motor driver motherboard is new but not working plz help

thank you , here is my code that lets you select the seconds per revolution with the "n_seconds_per_revolution" variable, to change the direciton you can toggle the "b_backwards" boolean from 0 to 1 or vice versa
```c
int a_b_stepper_pin_number[4] = {9,10,11,12};

int step_number = 0;
void setup()
{
int n_i = 0;
while(n_i < 4){
pinMode(a_b_stepper_pin_number[n_i], OUTPUT);
n_i++;
}

}
long n_time = 0;

int n_max_stepper_pins = 4;

int a_b_stepper_pin_voltage[4] = {0,0,0,0};

long n_stepper_pin_modulo = 0;

int n_steps_for_full_resolution = 2048;

float n_seconds_per_revolution = 10.0;

int n_minimum_millisecond_delay_between_steps = 2;

// 10sec * 1000ms = 10000ms / 2048steps = 4.88...
int n_calculated_delay_microseconds_for_seconds_per_revolution = ((float) n_seconds_per_revolution*(1000) / n_steps_for_full_resolution)*1000;
int b_backwards = 0; // direction

void loop()
{
// one loop counts as one step!!
n_time++;
n_stepper_pin_modulo = abs((3*b_backwards)-(n_time % n_max_stepper_pins));
int n_i = 0;
while(n_i < 4){
digitalWrite(a_b_stepper_pin_number[n_i], n_stepper_pin_modulo == n_i);
n_i++;
}

if(n_time >= (__LONG_MAX__)){
n_time = 0;
}
delayMicroseconds(n_calculated_delay_microseconds_for_seconds_per_revolution);

}
```

its was a good explentaion but it showed a erro ron my screen

I don't think you are supposed to drive this motor at 12V. This motor comes in two versions, one 5V and another 12V. So the 12V option on the driver is probably for the 12V version. I also tried to raise the voltage to above 5V on the 5V motor and it did overheat.

If you want to get really down to the nitty gritty, you can hook this up to a decade counter which is triggered with a 555 timer.

it is cheep good but slow

Why does it need the driver?
