I found a battery holder that holds 4 AA batteries Amazon.com . The battery holder has a snap connector at the side , so I was going to use a 9V I Type Battery Snap Connector here's the link Amazon.com . I was then thinking I can solder a 2Pin Dupont Cable 2 Pin Female Jumper Connector Wire [here's the link https://m.aliexpress.com/item/2255800014922431.html?gatewayAdapt=Pc2Msite ] to the 9v type battery snap connector wire then connect that to the Elegoo ULN2003 driver board , here's the link to that Amazon.com . Will this work to power a stepper motor only need the motor to work for 10 minutes and only run when an IR breakbeam detects movement.
This board is for unipolar stepper motors only.
It will work for a motor with low voltage and low current.
you forgot a link to solder iron and soldering tin
will power a 5V 28BYJ-48 stepper with the ULN2003 driver for a couple of hours.
Are you only using one driver? If so the 5v from the Arduino will be enough, if you need more, I would use an Arduino Mega
That's a good joke 
Sweet , that's more than enough.
I have used the 28BYJ-48 stepper motors before with their drivers and used an Arduino Mega to power it with no outside power supply (just realized you weren't replying to me)
This is a tutorial of one of the motors being powered from the Arduino itself
No, the motor is powered from USB. It won't work with a different power source.
That's a good joke.
That is a very low power low speed stepping motor. A lot depends on what the OP wants to do with the motor, we have very little actual detail about this movement, such as what it needs to move.
In most cases you need an external power supply and a driver to do much shifting with a stepping motor.
For that particular motor though see:-
And it's pretty rubbish.
Much better to use a TPIC6B595 for the 28BYJ-48 stepper motors, this can drive two motors per chip and is controlled by just three pins - even for several motors.
If you have enough power from the battery or whatever the other power source would be why not? It's not like the computer exceeds the max power supply rating.
The on-board voltage regulator is the limiting factor. Connect every alternative supply directly (separately) to the motor driver and to the Arduino and it will work because the Arduino then does not supply the motor by its low power regulator.
No, that's a Google search result page.
My bad, but you still get the idea, basic tutorials show how to power this motor and it's not from an external power supply, like Grumpy Mike said though, if whatever the motor has to do requires more torque, then more power needed is obvious.
Sorry, we don't get the idea. 
The Google search page lists multiple YouTube links. You have not cited a particular tutorial, and it would be somewhat rude to expect others to spend time trawling through hours of YouTube to see what foolish advice is given - after all, we already anticipate that. 
If you are saying that these tutorials describe drawing 5 V from the "5V" pin on a UNO and given that the 28BYJ-48/ 5V steppers draw 100 mA per phase except when driven by a ULN2003, then two phases drawing 100 mA each probably can be coped with by the USB supply purely for the purpose of an exercise.
Not sure however what the OP is proposing to do with his four-AA-cell battery as we have no actual detail. 
Using a USB supply to power a 28BYJ-48/ 5V stepper in a serious application however is anything but advisable. 
Ok first of all, calm down dude, I'm not the one being rude. Second of all here's a link if you need it right here and you're right we don't know what he wants to do with the stepper motor but unless your "serious application" means high torque, it's not like it is just for demonstration purposes. I made one of those CNC plotters like the one here with using the 5v and the driver.
I'm am just saying that he hasn't described anything that he's gonna do with the stepper motor and you can power it without an external power source OK
