- Sat Sep 28, 2019 12:38 pm #83959 So I made this schematic and printed it out on a PCB. It is not working, some time it does, but more often it doesn't! I can't debug the D1 mini don't know why! Any advace? Yeah, I know, probabily I'm missing something stupid.
Thanks in advance!

How about telling us what is not working?

And if you can, include a good clear picture of the board and how you have it wired. Sometimes things are done schematically correct but functionally wrong.

It runs fine for some times (a couple of hours I'd say) then it stop reading the correct temp (just returning -127.00 that as far as I know is an error code for the DS18B20) and looks like it is hanging or something! I can't even reset it at that point and I need to wait some times with the mini unplugged before being able of doing something again!
Here there are some pics of the board I made (the black/blue stuff on top is just some leftover of the blueprint foil).
