wrong section?

I am struggling with an application that I have in mind for the Hall effect sensor. What I want to do is build a simple detector that has a binary output which indicates whether or not current is flowing. I do not want to use a micro controller for this as that is overkill and takes up too many resources. My problem is that the zero-point on the sensor is 2.5V and not 0V. How do I detect if the output of the sensor is above that zero-point? I am totally out of my depth here with this one. Thanks.

Seems to be my lucky day. I had watched some videos on YouTube last night and today and was amazed by the "How they do it feeling" when I saw them displaying all of the details like Power, Current etc used by the LEDs on an LCD. Now I know.

These appeared to be in the wrong section

so I didn't respond but would like to.

I don't really think they are in the wrong section, as they both mentioned topics covered in the video. In fact, I answered @Codeslinger

I suppose if it evolves into a tangent about building his "non-microcontroller" version of the project then I could see your point.  A new thread asking how to do this may be more useful.

Feel free to add your response there (or here), I usually only move topics when they are definitely in the wrong section. Usually, I move ones in "suggest new content" that seem more like general questions or observations.

And I don't always move them just to exercise my supreme authority over the forum (although I'll tell you a secret, Codecage has as much supreme authority as I do). I usually move them to make it easier for someone trying to find specific info among the over 15,000 posts we have collected here!

But I do appreciate your exercising due diligence!

Ok.

Could you delete this thread?

You know, when I first saw the above response, I wanted to really let loose.  Instead, I have spent a couple days contemplating an appropriate response. 

People come into forums and ask questions because they are frustrated and are seeking help with a problem that they cannot solve on their own.  They have spent unknown hours wrestling with it and just cannot come up with a solution using the resources at hand.  At that point they turn to a forum somewhere and post their question there in the hope that someone else may know the answer or at least point them in the proper direction.  Imagine how dismaying it is to receive a response of "[This] appeared to be in the wrong section ... so I didn't respond but would like to".  Of what use is that?  It neither answers the question nor does it redirect the question to the appropriate location.  All it does is send the message that says "Your question sullies the purity of the message board, therefore you are not worthy of help."  

I have encountered similar attitudes when reading in other forums and thus have generally refrained from seeking help in that manner.  I had hoped that things would have been different here.

Honestly it wasn't like that. I wrote:

so I didn't respond but would like to.

I wasn't feeling any negative thoughts about the posts or the posters.  I just wasn't sure if I would be doing the right thing to respond in the same thread and thus started another one.

I have been castigated in another forum for "hijacking" a thread because my response was  "off topic" and am very sensitive to not make the wrong move which apparently has resulted in me making a wrong move here.

 It neither answers the question nor does it redirect the question to the appropriate location. 

But that was not the case. I did redirect the question to another location until Bill put me right and I instead returned to the same thread and responded to those questions asking Bill to delete this thread and thus my mistake.

I sincerely apologise for making you or anyone else to feel that way as it wasn't my intention.

I think I have a track record in these forums of responding, even when others have not, to help someone with their projects?

I had hoped that things would have been different here.

Things are different here.  Both  Codecage and Bill will see to that. In future I will simply respond and let   Codecage or Bill redirect the posts.

May I also add a big thank you for responding otherwise I would not have been aware of giving offense.

@robotbuilder and @codeslinger

Having spent almost half my professional life on forums, I know you both are correct. How the people coming in to the forums see at things, how the admins see them from a completely different perspective and also how things get messy at many instances - I have seen them all as well.

Somewhere I do feel, it is us who interpret things at times. Yes, I agree, there are times when a thread does not get the needed response, there are other times when you unintentionally have to bump up a thread just because things have changed or you need to add something extra or even ask something related (which was never asked/discussed on the thread earlier).

I do also admit, that things are similar here as well, just because we are humans who operate (administer, post, ask, reply, visit) this forum.

@codeslinger - brother, things are better here - despite some of the issues as you and robotbuilder mention on the above two posts/responses - the admin does go out of the way to fix things if there was an error - I can say so because I experienced it live - I had posted one in probably the wrong section (I admit, I never knew or cared to know that there was a subsection for the same, back then) - and that post was fixed and placed to its needed location.

Personally, because we have such a great team behind the scenes and a sensible set of members, I do not feel scared or fear or hesitation to ask. If you also would note, rootbuilder asked the admin to get rid of this thread once his doubts were answered.

So gentlemen, lets not let our past experiences interfere with the goodness that is around here.

Peace!

Are you saying that you don't see the importance of placing posts in the correct section? It is part of the forum maintenance, and while my moderators can easily move a misfiled post they are volunteers and it isn't fair to tax them with additional work on top of the fine work they already do without compensation. 

I'm sure that other forums" you are referring to have similar issues, despite what you might think running a forum is not a hands-off operation. Although I don't post here every day I certainly spend a few hours a day maintaining this site.

And we don't delete posts, we file them correctly. So that other people can find them among the over 15K posts here.

@robotbuilder was being cautious and was asking advice about responding to your post because he saw the potential of it sending the topic off into another direction, and he was justified in asking.  And you might note @codeslinger that I DID respond to your post, as I felt that since it involved a sensor in the video that it was appropriate.

You certainly have nothing to apologize for.

Feel free to "let loose" to me in a Private Message, as I still can't comprehend what you are so upset about.
