I am working on an arduino project and where I have a stepper motor connected along with other componenets, when I tery to print on serial the stepper does not work and if the stepper worked it interrupts the serial and sends irreadable characters. I am using 5V 28BYJ-48 with driver ULN2003 and <Stepper.h> library
How are you powering your stepper and driver?

Please post a schematic. Written descriptions are always more ambiguous than a drawing. Hand drawn, photographed and posted is fine. Include all pin names/numbers, components, their part numbers and/or values and power supplies.
Do not use pins 0 or 1 for anything if you are using the serial port (Serial.begin() is in your code). Those pins are for the hardware serial (USB) port.
Please read the how to get the most from the forum post. The post contains information on what we need to know in order to help you.
What Arduino board?

And, if you're using your Arduino's 5V output(with or without USB connected), consider:

I am powering them form an external 5V adapter
Sorry for not asking properly, I was using the oins 1 and 2 and when I changed them to 11 and 12 It worked, Thank you!!
The problem was in the pins that I was using for the connection between ULN2003 and Arduino, as I changed 1,2( used for serial hardware as pointed out by @groundFungus ) to 11,12 it worked, Thank you Anyways.

Good to hear. The power issue is one of the most common, so I thought it bore mention.
