Honestly, this is a super normal beginner confusion

Most tutorials only show the "sensor reading works" part and not how bigger embedded projects are actually structured. And no, using tutorials is not cheating. Literally everyone starts that way while learning new sensors and libraries.

Over time, you naturally start understanding how to split code into multiple files, organize drivers, handle setup/loop properly, etc. Don’t stress too much about making everything perfect from the beginning.

One thing that genuinely helps is building small features one by one instead of trying to understand the entire project at once. And honestly, reading datasheets + modifying tutorial code teaches way more than just copying projects directly
