First, please take note of time date stamps on topics… this is a old post.
Pick the topic, and there is probably some form of tutorial out there for it… but it’s effectiveness is entirely subjective and dependent on one’s learning style and aptitudes. For Blynk, we have Documentation, Help Center and Sketch Builder (And not all of those were even availed when I started - about a year ago). The forum and other talented users help… but some rely too much on “fix it for me” hand holding.
I, for one, really need handholding almost every step of the way (even when younger - undiagnosed learning disability traits and all that)… But reality dictates differently, so I instead hold my own hand and start looking for examples that I almost understand, then while “applying” them (if able) I take them apart for further trial and error type study.
Those that are willing to learn, do, and many become beneficial to others in turn…those that are NOT willing, eventually leave.
