Hi everyone,
Please, Ive been building and circuit board for arduino and it happend that I accidentally connected 12V to 5 arduino mega analog pins. There wasnt runing any program with monitoring the pins, however the board now isnt recognized by windows.
What should I do? What is broken? Is it repairable ? Is there anything I can do to fix it ?
Thaks for your answers.
Well, can you reliably solder smd parts? Do you have the test gear and enough time to actually test everything ?
If the answer is no for any of these questions, get a new board.
Thanks, I thought so 
So many hours spent on creating the circuit, then one mistake and I screw it all up.
Im such an idiot
You're not alone.
I'm an idiot too, but on a much larger scale (and different subject).
You are only an idiot if you continue to repeat the same mistakes. In other words, learn from what you did.
Personally, I continue to learn how to make bigger mistakes. XD
I wont make the mistake again. I figured out what I did and I fixed it qickly, but sadly the mP was already burnt. Its sad that I cant use it anymore. Perhaps if only analog pins would burn, it still could use it for digital pins.
There goes 21 euro for another one
Would be nice if it had a fuse or something. And it would be nice too, if there would be a version for 12v.
It appears I can connect it. The RX and TX start to blink but then just ten onboard led blinks and Im not sure If I did it in the program. Maybe the controller is trying to say something to me. But I guess Im just imagining things.
