From my perspective, the short answer is “Yes!”.
I came into CE knowing some electronics but not enough to be confident to think that I could create my own devices, though I dealy wanted to. CE has given me enough background knowledge and skills that makes this possible. The videos usually emphasise the focus on the data sheet when considering a design along with shopping for parts and at some point some layout considerations. I tend to think, It is not about the device to be built in a project so much, but about the means to get the job done and what needs to be considered along the way.
As I say, just my perspective.
