You can't see electricity (yet) so you need the next-best thing: multimeters, oscilloscopes, logic probes, debuggers, and spectrum analyzers. You know what, forget the spectrum analyzers. You RF people sicken me.

On “Working with a goddamn Oscilloscope”
Zack Freedman's latest video is a great intro to using an oscilloscope. link to this video
Using any scope made in the last 15 years or so is like trying to properly form a tar command, if you aren't already extremely familiar with the tool you need to do everything in baby steps while frequently checking the manual.
Scopes are great for getting qualitative information about a signal or precise timing information about signals, but decoding protocols like SPI varies a lot from model to model. The rough steps are:
- Get familiar with the protocol itself. Understand the roles and logic levels of the different lines, clocks, data, chip select, etc. Keep the timing diagram handy to refer to when you are…
