How do you usually approach learning new technical concepts outside official documentation?

When working with microcontrollers, embedded systems, or related technologies, official documentation is usually the primary reference. However, many developers also rely on external learning resources to better understand concepts, workflows, or practical examples.

I’m interested in how others here approach learning beyond datasheets and reference manuals. Do you prefer community forums, structured tutorials, project-based examples, or independently reviewing different informational websites to compare explanations and layouts?

Occasionally, I look at general technical or informational websites such as noopener referer Delta iOS Executor to observe how technical content is structured and presented for readers. It helps me understand what makes information easier to follow, especially for users at different experience levels.

I’d appreciate hearing how others evaluate and choose supplementary resources when learning or exploring new technical topics.
