It got migrated cause it mentioned RPI. That's all. By the same mod who migrates any question with Arduino or Cars in the question as well. Within minutes of being posted. With no one down voting or close voting. Single handedly. Even though we have a don't migrate to betas or don't migrate crap policy. Migration Guidelines Re: Arduinos
The only way for this to stop is if users and mods of those sites continue to complain.
See http://meta.mechanics.stackexchange.com/questions/1464/led-lights-questionhttps://mechanics.meta.stackexchange.com/questions/1464/led-lights-question , Question migration anti-patterns: Skeptics SE, Post Moved to Rasberry Pi Site, Why was http://electronics.stackexchange.com/questions/182864/arduino-relay-shield migrated?, Another bad migration to Arduino for another examples.
Most notably, even another mod has point out these "knee jerk" migrations:
Yes, Nick tends to knee-jerk migrate any post that merely mentions Raspberry Pi or Arduino, without considering whether the question is really appropriate for the destination site.

I've basically been told to shut-up about it since apparently I'm the only one that cares on EE.
