A good question gets a fast answer. Spend 5 minutes structuring your post and people can actually help.

Use this template

1. What are you trying to do?
One short sentence on the project goal, not the bug.
Example: "Driving a 28BYJ-48 stepper from an Arduino UNO over ULN2003 to rotate a camera mount 360 degrees."

2. Hardware list
Exact part names. Brand and model. Links to product pages help.

• Arduino UNO R3
• ULN2003 stepper driver module
• 28BYJ-48 stepper 5V
• Generic 5V 2A wall adapter

3. Wiring
Photo of your wiring on a breadboard, or a Fritzing/diagram. Pin numbers in text are fine if simple.

4. Code
Minimal sketch that reproduces the issue, in tags. Not the entire project. Strip what isn't relevant.

5. What you see vs what you expect
"Stepper buzzes but doesn't rotate. Expected one full revolution every 5 seconds."

6. What you already tried
"Swapped the driver, swapped the stepper, swapped the USB cable, tried external 5V supply."

7. Error messages, exact text
Paste compiler errors and serial monitor output verbatim, not screenshots.

Things that get questions ignored

• "It doesn't work, please help"
• No part numbers
• Screenshot of code instead of pasted code
• A wall of text with no structure
• Multiple unrelated problems in one thread

Good luck. The faster you give us the boring details, the faster we can help.
