It shouldn't have been. Migration should only happen when something is OFF TOPIC HERE, and on topic there. This is clearly an on topic Electrical Engineering question. The mod who migrated it single-handedly does this to any question that even mentions a car, arduino, or raspberry pi to those other stack exchange sites.
Flagged for migration review by Mechanics mods.
Update: The question has been closed on Mechanics as Migration Rejected. It can be voted to reopen here now.
Further update: The question has been reopened here.
