I don’t know if other errors exist (this is my first board) and i dion’t even know how to debug the pcb.
I will upload the schematic and the pcb file here.
I understand that people have their own problems and maybe don’t have time for this.
I want to know that i am willing to pay someone who will look into this (paypal).
I think you can get the help you need if you are willing to put in the effort to provide more information.
For the barrel connector power, is it set to positive or negative pin polarity?
Can you upload the schematic symbol files that you used? U1, U2, and U3 are absolutely required to have any chance of knowing for certain where the problems are.
Verify the connectors are not reversed. i.e. are the connected to the correct part of your shield circuit?
On an empty board (i.e. no components) apply 5V power and verify it goes where you think it should.
On your schematic, it looks like your power and ground are connected just below the barrel jack (on your schematic)
Baby steps. Don’t try to troubleshoot everything at once. You could do it a number of ways but one way is to take a blank board, Add the connectors but no other components. Using a volt meter verify your connections are what you expect.
I’d like to say - you are very brave as you start your electronic adventure from something like that. I don’t know what arduino shield means. For me shield is a piece of metal closing the PCB inside it but it looks that here shield means something different.
I have started (many years ago) with simple external antenna + LC + diode + headphones to receive AM radio station.
Prepare yourself that at the beginning of electronic hobby most of the time you’re in a state of “why the hell isn’t that circuit working”. And the more such problems you solve yourself the more you learn.
The more problems will be solved for you by anyone else the less you will learn. If someone points you “here is the bug” and explains you why then it at once seems being so obvious that then you fast forgot it. If you spend hours searching a bug then when you at the end find it you will remember why it was wrong forever.
It is good for your mental health if you do not assume that shortly as soon as you design a circuit it will work well immediately.
Wish you everything good in your adventure with electronic.
Hmmm i don’t know what you mean. The middle pin is Vcc and the other two external ones are GND
What extension do these files have? I cannot seem to find them. But i found my custom symbol library files, they are {bck, dcm, lib} files. Are these the ones?
EDIT: I uploaded everything i have for this project in a zip file. Please look at the original question.
Thank you very much!
Thank you for your kind words, but its a fun learning experience when you work for you hobby.
But if you are tight on deadlines and you just want to deliver your work and it does not work - at least the Hardware part, then it’s not fun.
The biggest problem is i dpn’t know what’s to blame, as everything looks good, and i don’t know how to debug this thing.

Barrel jacks are available in center pin positive and center pin negative. If your barrel jack polarity was reversed it could cause problems. As @halachal reccomends, get a multimeter!
I think you might be looking at the whole board at once and find it overwhelming. As I suggested above, you start with simple things like is the power and ground connected the way you think it should (by your schematic. For instance; find the ground pin on your connector, then with the ohmmeter you will need to get measure from the connector to every component pad you have connected to ground. Then do the same with +V
Then make sure the +V is not connected to ground.
Move on to the reset and do the same.
You started with an advanced project. Which is fine but now you have to slow down and go in baby steps.
