Then, to answer your questions.

1. Yes, please do make sure all your images are in the format 1920x1080. If you are using external images, try using images or format them in some way that they also follow the guidelines. If you are using other people's images, you need to make sure if follows the correct copyrights. Your images look fine, and we don't need to remake them!
2. If the introduction still makes sense, you can leave it. However if it is somehow different from the tutorial you copied, please add a sentence or two about what your tutorial is about.

again, thank you for your contribution! ⭐

Hi @MessiahJa. Please sync your fork by following this tutorial:

https://docs.github.com/en/pull-requests/collaborating-with-pull-requests/working-with-forks/syncing-a-fork

Your fork is currently very outdated compared to Arduino's repository and that is causing the automated "Content Linter" check to fail. It should be as simple to do as clicking the button shown in the tutorial I linked above.

@per1234 I was making new changes at the same time as your corrections so I could not commit your suggestions since they became outdated. I corrected the spelling errors, shortened the title and added "proper" descriptions to all images. Thank you.

You are welcome. I find GitHub's "suggestions" feature useful for unambiguous communication during PR reviews, but the PR author is always welcome to implement my suggestions however they like (if at all).

Please check the results of the latest CI run. There is good progress toward a ✔️, but still a few problems that will need to be resolved:

#222 (comment)

@per1234 Is there any tutorial that could show me how I could use CI? I saw that the results do not update and it has to run again but I've not found any tutorials on it.

Is there any tutorial that could show me how I could use CI

There is general information about it here:

https://docs.github.com/en/actions

However, that is only about the "GitHub Actions" framework the continuous integration system of this repository runs on. There isn't anything there specific to Arduino's own checks.

The "Spell Check" check that runs is from this excellent tool named codespell:

https://github.com/codespell-project/codespell

If you install that on your computer, you could run codespell on the projects yourself using a command like this:

codespell -I "scripts/resources/spell-check-ignore-list.txt" --skip="*.svg,*.dxf" ./content/

The "Content Linter" check is a custom tool created by Arduino and hosted here:

https://github.com/arduino/content-lint

I saw that the results do not update and it has to run again but I've not found any tutorials on it.

Unfortunately, there is nothing you can do about that. Arduino has configured the repository so that a maintainer must approve the CI runs for PRs from new contributors. That means there is an unfortunate delay between you pushing a new commit to the pull request and when one of the maintainers notice that an approval is required.

If you submit additional pull requests here after this one has been merged, the CI system will run the checks automatically.

Should we close this PR? #193
@MessiahJa

@marqdevx If nothing is left to fix then yes! :D

@per1234 if you are happy with the tutorial now, could you please give an approving review? We are blocked from merging atm ⭐

@per1234 Thanks for your evaluation!

@jhansson-ard Should we remake the pictures with an schematic view?

Also I've tried to render it locally and everything seems good, no issues on the formatting side. ✔️

@MessiahJa We are making some schematics pictures to replace the photos you took.

Also next week I will make some small changes, we will wait for your approval before merging it. 😄

Hello @marqdevx !
Is there anything I can do to help out with the changes and schematics? I have worked a lot on this and would love to see it included in the Arduino Docs. I'm working on a new one and want to have this merged before pulling the next tutorial.

Sorry, I couldn't work on it yet.
I want just to make some small changes to fit our style guide, any major change.
I will jump on it ASAP

Its been more than a month since I last followed up. I put a lot of time and effort into creating this and was hoping to make a bunch more back to back but there has been no response from your team. @marqdevx

Hey @MessiahJa!

We are currently in the middle of vacations, but Pablo will be back next week. I will make sure he takes a look at this PR so that we can merge it as soon as he is back.

Thank you for your patience 🙏🏼

I've changed the tutorial folder (the final link) to
https://docs.arduino.cc/tutorials/uno-rev3/ matlab-pwm-blink

https://docscontent-marqdevxcommunitymatlabpwmunop.gtsb.io/tutorials/uno-rev3/PWM-using-MATLAB-Tutorial

I'm having issues opening this page

@MessiahJa content seems ready, im waiting for your confirmation 😄

Cant wait, lets go.

What does it say when you access the preview

Then lets merge 💪

@MessiahJa It is public https://docs.arduino.cc/tutorials/uno-rev3/matlab-pwm-blink

It appears on both Uno R3 and UNO R3 SMD

Thanks for the contribution!! 😄

What does it say when you access the preview

It worked. Thank you very much for your help @jhansson-ard, @per1234 & @marqdevx
