Yes
Ok, thanks for your help!
Try this code.
A switch connected between pin 8 and GND closing will make the stepper run for 5 seconds.

I actually already have working code for the stepper, thanks anyway!
So i tried 4 aa batteries, and there is even less power, am I doing something wrong?
We will never know because you are not showing us what you have done.
Sorry, I did exactly like that schematic i sent you.
But you have not shown us a good image of your actual wiring for us to review.
It'll be hard to show, but i can try
Is that a 2 AA battery holder (3v) or 4 AA battery holder (6v) ?
You need 6v (4 AA batteries).
The + side of the batteries goes to the motor driver board 5v terminal.
The Arduino is powered from an external supply.
Hi,
What 4 pins are you using for control?
Are they the same as in the code you are using?
Using one of those buttons to switch power is not good, they have some resistance when ON.
Thanks.. Tom...
Hope you aren’t trying to power the Arduino from the batteries !
Its a 4
Show us a close up picture of your Arduino wiring.
Yeah, believe so, what switch would you recommend?
Ok, i will when i get home
If you have a voltmeter, measure the battery voltage when your sketch is running.
I think maybe thats what im doing, sorry, i dont know much about this🤦
