My son and I tried to get the stepper to work today. We used the stepper library for the software. The lights are blinking on the board and the motor vibrates, but the shaft doesn't turn. Any ideas?
Yes - don't hijack threads, post code and schematic.
Telling us what board and shield you're using would be helpful
I'm guessing your using the standard controller that is usually sold with the motor.
If all 4 of the lights blink and the motor vibrates, it's likely that the 4 wires from the controller to the Arduino are in the wrong order.
You can fix that either by moving the physical wires or changing the pin numbers in the code.
