A question was asked regarding a connection on a schematic.

Is there a mistake in this microcontroller schematic?

Which received an amazing answer detailing the misconception and proper/updated design practices.

Why was this migrated?

    \$\begingroup\$ I don't know. It is clearly a question about schematic drawng practices, not about Arduino. @Nick -- why did you do it? \$\endgroup\$ – Dave Tweed Aug 3 '16 at 2:10

    \$\begingroup\$ I was very surprised when I saw that as well, and I always propose migrating Arduino software questions. This question had nothing to do with Arduino except for the label on the schematic. \$\endgroup\$ – pipe Aug 3 '16 at 13:12

    \$\begingroup\$ its almost as if a bot just searches for Arduino and auto-migrates \$\endgroup\$ – JonRB Aug 3 '16 at 14:51

    \$\begingroup\$ I believe this is not unique. In the last couple of monts, I think I have seen clear, electronic engineering, questions which have been migrated to the arduino.se. I had started to assume there was some sort of policy to help the arduino.se be successful by pushing content, and hence visitors, there by migrating questions. I agree, questions about Arduino software are usually clear enough to migrate without much argument, but hardware questions are often not Arduino specific; I don't think migrating hardware questions should be 'automatic' just because it mentions 'Arduino' in the question. \$\endgroup\$ – gbulmer Aug 3 '16 at 17:50
  • \$\begingroup\$ Yet something like electronics.stackexchange.com/questions/248522/… specifically about the Arduino 5V power capability isn't. \$\endgroup\$ – Passerby Aug 3 '16 at 17:56

    \$\begingroup\$ I would think that questions involving Arduino connections to peripheral parts should not be migrated, even with an Arduino tag. Many questions involve connections to mosfets, H-bridges, ADC's, charger IC's, LED drivers, etc. Mistaking how an Arduino can source or sink voltage/current is not a reason to migrate either. Many are simple interface and voltage translation issues. \$\endgroup\$ – VTNCaGNtdDVNalUy Aug 3 '16 at 20:50

    \$\begingroup\$ Surely the arduino community will benefit most from the answer... \$\endgroup\$ – PlasmaHH Aug 4 '16 at 10:42

    \$\begingroup\$ "its almost as if a bot just searches for Arduino and auto-migrates" -> Interesting as there is a bit of a history of that happening WRT raspberrypi.SE as well. Someone should track this bot down and correct its programming ;) \$\endgroup\$ – fizzle Aug 5 '16 at 20:19

    \$\begingroup\$ @starfish You can look into the arduino tag and notice what proportion actually gets migrated, how much gets closed (and by whom), how much remains intact. \$\endgroup\$ – Nick Alexeev Aug 5 '16 at 23:36

    \$\begingroup\$ @Passerby: Thanks for raising this. I've had a few answers kicked over to Arduino which doesn't support MathJAX and so the answer got messed up. I asked Nick the same question and pointed out that my answer didn't mention the 'A'-word and that it just happened to be an Arduino schematic. \$\endgroup\$ – Transistor Aug 9 '16 at 9:52

The question in question is back from Arduino.SE and in our custody.

    \$\begingroup\$ But you still haven't explained why you migrated it in the first place. \$\endgroup\$ – Dave Tweed Aug 6 '16 at 14:16
  • \$\begingroup\$ @DaveTweed Arduino folks would benefit the most from having one of their schematics analyzed. So they might have as well hosted the question. \$\endgroup\$ – Nick Alexeev Aug 6 '16 at 14:36

    \$\begingroup\$ But there was no actual problem with the schematic. The only problem was with how the OP was reading it. \$\endgroup\$ – Dave Tweed Aug 6 '16 at 14:47

The question mentioned "arduino" several times, including once prominently in the title. Arduino questions largely don't belong here. We usually have to waste time closing and downvoting them while they noise up the site, so it is understandable that when someone is in a hurry, they just migrate it at the first sight of "arduino". That's the right action in most cases. Give Nick a break.

This should be a strong warning to every ardweenie out there. If your question is actually about a arduino, don't post it here. If it's not, then you should be able to replace all mention of "arduino" with "microcontroller" or "microcontroller development board". In that case, make the substitution and post it here. Put another way, never mention "arduino" in a question here. If you feel you need to for the question to make sense, then that's a strong clue it doesn't belong here.

In this case, I edited the question to serve as a example of how the question should have been presented here in the first place. This wasn't about the arduinoness, so references to it were removed and the question still asks the same thing. While at it, I also fixed some other stupidities (Kelvin is not a unit of resitance, using component designators, including the relevant schematic snippet directly in the question). When askers fail to take this level of care, they run the risk of their question of getting closed, downvoted, or migrated. That's how it works. Get over it.

The golden rule: Don't post crap. Or anything that looks like crap from a quick glance, since you then may not get a second glance.
