| EE is my day job so I may be biased towards more formal resources. Sparkfun, Adafruit, etc have some good stuff to get you off the ground and building projects almost right away. I think they're great "taster" in how circuits work and what some of the components are for. Khan Academy has a course for EE, I haven't used it but I've used the site for other stuff like brushing up of my math. Manufacturers actually make some really nice training materials, if you like analogue stuff, TI's Precision Labs series is a great resource for that. Analog Devices has an intro to electronics wiki series too. https://wiki.analog.com/university/courses/electronics/text/... For a deeper look, an undergraduate electronics textbook will hold your hand from the very basics through to more advanced concepts. You can ignore some of the more advanced stuff like AC analysis and non-linear components for the most part (Unless they interest you!) I learned from this book (https://www.pearson.com/en-gb/subject-catalog/p/electronics-...) and found it quite approachable in how it laid out the basics before contextualising them as systems. Theres also the famous Art of Electronics which is a good book but personally feels a bit dated (even with the new edition) and really analogue heavy. A good reference manual though. |
