Collin's Lab: Schematics
Schematics are the map for every project guide a beginner will follow, and this 2011 episode covers the vital basics of reading them. Its most encouraging point is that if you can read a schematic, you can build a circuit before you fully understand how it works.
That makes it the bridge between watching tutorials and building from a diagram on your own. Watch it with any simple project schematic open beside it and match each symbol as Collin names it.
