YES! We really do need Circuit-Lab on here. This is enabled on EE.SE. So as to your feature-request, could the team pretty please consider enabling Circuit-Lab on here? I would personally use this on wiring questions, or anything that needs an electrical schematic. The Stack Exchange team looks for questions/posts that would benefit by having Circut-Lab, so ...

YES! We really do need Circuit-Lab on here. The Arduino is more than just code. It is hardware, software, IDE and core libraries. This SE needs efficient/effective methods to communicate all of these functions of the Arduino eco's or framework. Note SO's arduino tab has many questions with long winded descriptions of circuits, that work in conjunction with ...

Yes, a formula feature is needed. The Arduino has both hardware and software functions that are often best described as formula's when asking questions. PID loop's Filters often filters need to be calculated for the Hardware and then worked with in hardware. the PWM used with RC to make A2D can be best described with 2PiRC formula. Polynomial CRC's ...

Interesting idea, but I thought things were worse than that. :) I've noticed quite a few answers (including some of my own, heh) which do not get a single up-vote, let alone being accepted by the asker. At least with an up-vote, the system (I think) considers the question answered (maybe with a couple of up-votes, I'm not sure). (Not accepted, but at least ...

Another question that benefits from a decent circuit editor: How to switch an external circuit with Arduino? This is typically what happens when none is available. Now I have to grab pen and paper and follow the description word for word while drawing what I think the author meant. Someone else may draw another circuit. And the people who answer, need to ...

Fritzing appears to be the official standard for Arduino circuits. (Site currently mostly down at the moment.)

Why do some pins have a different PWM frequency? Above mentioned question will benefit from MathJax. The formula when written without proper formatting quickly gets hard to read.

If there isn't enough information to answer the question then I think "Unclear what you're asking" is a suitable close reason.

This is enabled, and on by default in the programming tag. You can use language hints to fine-tune the highlighting if the defaults aren't acceptable.

simulate this circuit – Schematic created using CircuitLab While I generally agree with Pops, I looked at some of the other sites with this setting enabled: Amateur Radio Raspberry Pi EE It seems to me that the list fits into what you might call hobbyist electronics/embedded systems sites. So I'm a little more convinced the feature will be used for ...

You sure can! A new "infinity logo" should be showing up on computers near you soon.

Another typical example of where circuit diagrams are required. Project Showcase '14 Every answer with that should probably ultimately contain a circuit diagram.

Another perfect example why we want something trivial as the ability to author formulas is in this question: Why voltage at AREF is given by Vin * R2 / Rtotal

I just want to echo what Nick Gammon has said and just explain my methodology for improving this. The system only considers a question as unanswered if it has no answers with a score greater than 0. There are a lot of questions out there with good answers, just none of them have been up-voted. So when I get a chance I go through and vote on answers that need ...

Simply put, if they can't be answered, they should've been closed already. Too broad is applicable if they don't have enough information in their question to narrow it down to a specific solution (you end up getting a lot of very scattered answers). So, close questions if they can't be answered. They'll get deleted after some time automatically.

I'm not sure documentation per se is going to be useful. As Nick has noted reading documentation is something that many of our incoming users ("Ardueenies") are averse to doing. Another thing they seem averse to doing is searching. The number of duplicate questions we get seems to be rather high. So instead of spending our time on documentation, it may be ...

A tag should be created (from scratch) if you use it. It doesn't have to exist in advance.

I would say some caution is required. Just because the OP has vanished, it does not mean that the question is redundant/useless. I Just remember what I heard from a lecturer back at college, many moons ago: If you have a question, but are too scared to ask it, for fear of looking the fool, then fear not. If you have thought of that question, then it is ...

Here is one. I posted basically the same question on both Arduino SE and Electrical Engineering SE. https://electronics.stackexchange.com/questions/307586/need-help-calibrating-adc-input-using-a-voltage-divider How can I seriously calibrate ADC voltage readings with Arduino Nano? The answer I came to in EE SE made good sense to share on Arduino. I ...

I propose we do the following: Create a "Question Checklist" help page (hopefully with a better name) that provides a list of clear, simple and very specific actions that beginners can take to improve their questions. (See below for my initial go at this.) Change the "How to ask box" to add, "Review the question checklist page before posting your question ...

With respect to the adage, "Go read the datasheet," datasheets contain formulae such as: Figure 1 – Waveform frequency equation. Figure 2 – PWM frequency equation. Figure 3 – PWM resolution in bits equation. Figure 4 – Maximum external clock frequency equation.                     Figure 5 – Equations to calculate the ratio of the incoming ...

I don't think the SE team would implement this. There has been various talk about this before (formal and informal), and the consensus is to leave accepting for users (especially ones who can't yet vote), and for everyone else to upvote. For a question to be considered unanswered, it must have no upvoted or accepted answers.

Update to #3: Ask about... Specific issues with Arduino boards, clones, code, and the Arduino IDE Real problems or questions that you’ve encountered Don't ask about... Anything not directly related to Arduino Any question that doesn't require knowledge about the Arduino platform to answer (Try Stack Overflow for general coding ...

I'm a little late to the party here. Perhaps I should have created a new meta discussion. I was part of the first(?) Arduino.SE closed beta which was eventually merged into EE and SO. This was the favicon I created for that purpose. Licensed under the Creative Commons Attribution-ShareAlike 4.0 International License. If that license is incompatible with ...

It seems we moderators have the power to add a new reason for closing as off-topic, although it needs more than one of us to approve it. To guide us, please vote up Majenko's suggestion if you approve of it (and vote it down if you don't). Comments or replies can also be used to argue for or against this proposal.

I have done similar questions, such as How do you use SPI on an Arduino?. It is certainly OK to post a question and answer it yourself. The intent of Stack Exchange in general is to become a repository of useful questions and answers. Sometimes a single person will do both the question and answer, and at other times one person will ask a very interesting ...


2

You raise an interesting point, although the concept would probably belong to every part of the Stack Exchange network, and thus might be better put at https://meta.stackexchange.com/. You might argue that someone might answer a bad question, so upvoting a question just because it gets an answer might skew the results a bit. In fact, if every question is ...

It bothers me too that there aren't enough upvotes on Arduino SE. I am yet to come up with a good solution. As well as upvotes, bronze badges (eg. Student) are used to encourage good questions. One thing that doesn't work in our favour is that we have so many new users every day who ask their question, get an answer and then never stick around to pay it ...

Your question was blatantly off topic. If you buy a Dongfeng car and rip out the factory installed stereo, then buy a Fony™ stereo and fit it yourself, would you then go to a Ford dealership to ask how to tune the stereo to your favourite station? No. You'd get laughed all the way down the road. You do NOT presume to dictate to us what wuestions we are ...

Call for action: Go for the Vox populi batch and the civic duty batch. Note if you go for the "vox populi" batch do not star questions as you will not be able to get your 40 votes. I hope someone noticed some upvotes today. Tomorrow I try again for the "vox populi" There seems to be a suffrage badge for 30 votes as well :-)
