Probably an age thing, but I’ve never understood the point of Lego instructions. Or the sets. The whole point of Lego was creative free form building. Remove that & it’s dull as hell. It just becomes model building with poor quality models as the result. I’m happy other people find it fun, but to me it misses the entire point in favor of weak licensed “kits”.
It is a whole lot different from tinkering with arduino hats/sw, as frustration can creep in if things don't work as expected.
