C++ Components for ESP-IDF / Components for the Minimal Working Environment (replacement for #669)

[christoph-oberle]

📝 Description

For beginners it is not easy to establish a minimal working environment for the ESP32 SoCs with e.g. Wifi, buttons, LEDs and waking up from Deep Sleep. Unfortunately such a minimal environment is necessary to get things done. This article describes some components which help to set up this environment. By using C++ the complexity is hidden inside the component classes.

This is a follow-up pull request for pull request #669

I had to close the original pull request because I have deleted the forked repository.
Now after cleaning my GitHub contents I have created a new pull request with the exact same contents as before

🧪 Testing (Hugo)

• I have run hugo server locally and verified there are no build errors.
• I have checked the rendered output on Desktop view.
• I have verified that internal links and syntax highlighting work correctly.

@f-hollow , @FBEZ : This is my follow-up pull request for #669

I have rearranged my GitHub contents, removed the second private account (which caused my accounts to get flagged), created an organization "elrebo-de" and renamed my personal account to "christoph-oberle".

I have shifted the publication date from 30.03.2026 to 13.04.2026.
