Your question is Stepper Motor Operation. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Explain how a stepper motor works, including the rotor and stator roles. Describe how energized stator phases create a rotating magnetic field, how the rotor aligns with that field, and how pulse sequencing controls position. Include practical failure modes and the embedded-system controls you would use to detect or safely handle missed steps, overheating, and unauthorized motor commands.
