It would be nice if they showed what the end result would be like. One of the most frustrating things about the maker crowd is that every tutorial ends up painfully explaining breadboard connections - they're not addressing "how to fish" - just show the schematic and teach new comers how to read the schematic and make their own connections on the breadboard. 90% of the tutorials spend painful time showing "connect this pin over here in this breadboard hole". It's like teaching someone how to draw by saying "Draw this line here at 35 degree angle with this amount of pressure and length." The entire video here [1] is just looking at someone put wires together but doesn't show the final product in a satisfactory way. Everyone's breadboard will be unique - you can't follow step by step connections on a breadboard. You can however, just look at the schematic and hook up stuff on your own once you know how 1) breadboard works 2) how to read schematics. Both of these can be offloaded and referred elsewhere and the time spent in the tutorial should be about architecture, explaining the schematic,
why is it designed that way, advantages and disadvantages, etc. /rant
