thanks a lot anons, I'll try lowering the delay and also implementing parity. I'll tell you how it goes.
and, thanks for explaining how you learnt about UART, I'll check it out.
I've been making small projects with arduino for 4 years now (not regularly though), but I don't know where to even start with the basic stuff. I can make stuff work (I know the logic, I figure out algorithms in my mind) , but I'd really like to work with oscilloscopes and other stuff and just see how it works.
but then again, I'm self taught and I started as a 14 years old kid with 0 previous experience (18 now), couldn't make things regularly, so my expectations may be too high.

Trivial, get a coil winder if you are into radio or making your own transformers. Ali has one for ~$60 with a counter and it amazed me how much easier it made winding inductors and transformators.

>RULES
0. Electrics ≠ electronics. Appliances/mains/sparky stuff to /qtddtot/ or /sqt/. PC assembly >>>/g/
1. Search web first. Re-read all documentation/data-sheets related to your components/circuits. THEN ask. Show your work.
2. Pics > 1000 words. Post relevant schematic/picture/sketch with all part numbers/values/etc when asking for help. Focus/lighting counts.
2.5. State your skill level if asking an open-ended question.
3. Read posts fully. Solve more problems than you create.
4. /ohm/ is an anonymous, non-smoking general.

>I'm new to electronics. Where to get started?
It is an art/science of applying principles to requirements.
Find problem, learn principles, design and verify solution, build, test, post results, repeat

Look up "ground loop isolator".

Get rid of it.

it's an amplifier. it's supposed to oscillate
post the schematic already

>>1725090
yes. yes, you do. it's called engineering

>>1725088
kinda hoping the next OP uses this
