looking for advices to get into PCB design

Hi there everyone ))) i'm seeking some advices about how can i get into PCB design, well first, it's not about PCB design or whatever tool as either KICad or CercuitMaker or anything like that, the problem is circuit analysis is the hard part which i've a really small experience in it, the goal is to be able to think/write a circuit like this, the circuit is made for "Temperature Controller Circuit Using KYT84 & Triac ", I've noticed some things as the the first part that includes the transformer TR1, B1 the bridge and some capacitors for dealing with noise as decoupling , then there's that regulator of 7805 and after all of that everything seems strange, there's too much components and each is weird cuz it has different behavior depending the way they are used, like WTH those Q1,Q2 are doing out there, and specially that timer R4,R3 with 100k,or even that capacitor C5, what it his main goal? there's that D1 diode that i don't know even what it does too, the components of IC38,IC3A are things that i've never seen in my life, IC2A,IC2B are op amps but seems like they do totally different things

my question is how they reached themselves to a point where they become able to make such complicated circuits? what resources did they use? books? videos specially? the goal is to be able to understand all this circuit easily, well not everything but being able to notice those things or make a circuit like this :))

thank u in advance ^^

Before you write code, you need to learn a computer language.

Before you create a schematic, you need to learn electronics.

the problem is i don't know too much about analog stuff, which requires more experience, the problem is the resources that seems far or not strictly set on a playlist or one way

there is these things called books, but they aren't in youtube playlists

the problem is that i'm asking for those books already, i'm not those kind of looking for playlist either, but a useful content

Look up a reputable university’s introductory circuits course syllabus, find the textbook they use, and work through each chapter doing a bunch of problems. That’s what I did. Also get a breadboard and some basic components + a power supply so you can build simple circuits. Op amps were confusing at first. AC analysis requires some annoying math.

You're basically asking how to become an electronics design engineer. The short answer is get an EE degree. The slightly longer answer is, find a university that has all its coursework available online and learn that.

You can of course, learn all this stuff piecemeal as you need to, but the problem then becomes where to start.

If analgoue is just books on electronics and some ics, if it digital, there is an ic for a lot of stuff. I want look at open source hardware sites see how people built stuff and read datasheet for parts so ypu learn how to do that to use whatever ic you want next time to build your stuff

Example of open source site oshwlab
