I have taken a look at the list of recently migrated Arduino questions. I thought we had reached the consensus that questions regarding Arduino that involve a good deal of electronics are fine on this site. But I still see many questions migrated.
- ATMega328P-PU and 328P-AU about differences between ATMega chips, not specifically in Arduinos
- What bytes do I send to the MAX7221 to light an LED (in an led Matrix)? about interfacing a non-Arduino chip, which happens to be done with an Arduino
- Arduino - millis() about C, which happens to be about a function from the Arduino libraries but also applies in many other cases
- Arduino/C++ byte manipulation has nothing to do with Arduino: simple C - if anywhere, it should've been migrated to SO
I would like to do a general suggestion that if the community agrees according to vote counts on this question and its answers, this type of questions be no longer migrated or only if there seems to be support from the community (other than only from one or two).
As a moderator you're still part of the community and there is no reason to migrate away the questions you don't like if there's no support for this within the community.
This question, Operate Arduino Nano using variable voltage, was first migrated to Arduino. I had to flag it there to get it migrated back here. Such moving around of posts isn't be beneficial to anyone.
NB: (without sufficient rep?) you won't see this in the post history, but it's really true. I flagged the post on Arduino.SE and asked for a migration back.
Related: Can we stop the random migrating?; +22/-5; not a duplicate since this is a general request (which the other was as well actually, but this was massively misunderstood, even after emphasising that aspect of the question).
