Does anyone here, know of a good " I have an oscilloscope, but don't

now that I'm getting into more programming, analog/digital, and logic
circuits, I need to figure it out. Any help?

The best way is to start poking the probe into low-voltage circuits, to
see what's there. Of course, a knowledge of the circuit diagram could be
helpful.
Back when I was a tiny tot, there were these things called television
sets, containing tubes and/or transistors. A company called SAMS made
these wonderful repair guides called Photo-Fact schematic folders. They
had dozens of oscilloscope traces printed right on the schematic
diagrams, indicating what signal waveform and size to expect on each
stage of the circuit. They also had photos of the chassis (PC boards or
point-to-point wiring) calling out every component and every waveform's
test point.
But these were television sets full of yummy high voltage, and the
danger of getting a big shock or blowing up the scope probe was palpable.
