💬 Easy/Newbie PCB for MySensors

@sundberg84 Yes thanks I did so. But do not get any temp read out? Have al in space also the 4,7 k resistor.
this is my sketch:

You can try to measure continuity from sensor to VCC / Gnd and D3 on the atmega.

@gohan Not a solder problem I think. This is no short on the board it is just the angel of the picture hiding the gap underneath. :)
tried the same set-up with an other dallas sensor. still the same result.@mr_sensor - still, very strange. I have the exact same setup and it works without issues.
Try to do a continuity test between the middle pin of the sensor (touch the leg, not any solder-point) and D3 on the atmega328 chip (Do not power the node while doing this).
Try to do the same continuity test between the middle leg on the sensor and GND + VCC on the PCB.
Also, please report back the voltage between VCC and GND on the sensor. (Same, measure on the legs)

tried the same set-up with an other dallas sensor. still the same result.Still you should read and watch a few videos on YouTube about how to make good solder joints, because your board is not really pretty at the moment ;)
It's not difficult to make proper "volcano" shaped solder joints when you have learnt the few tricks you need, and it avoids a lot of hair pulling! -

@sundberg84 I did measure some things. Also replaced the arduino to be sure that it was working (did nt make a difference)
I found 3,3 volt between vcc and gnd on the sensor. Also between the data-pin of the sensor and the arduino there is continuity.
The middle leg on the sensor and GND + VCC on the PCB is not resulting in any continuity(I am not really sure if I did measure it in the right way. It is a bit hard to get gnd + vcc on the multimeter pin together). -

I would re-install the library or try anohter one as first thing to do because you said you have tried another sensor and pro mini right?

@sundberg84 I tried with other libraries, without success. Also changed the sensor for a new one, without any success. Only thing that made me wondering, now the sensor is on 3,3 volt? When looking at the net for samples, etc. some of them refer to 5volt? So could that be the problem here? Not providing 5 volt to the sensor?

@mr_sensor - no 3.3v is enough:
This is really strange... can you confirm it is the right markings on your TO-92 package (actually a temp sensor)?
You could try changing the pin to exclude a pro mini failure (if you have not swapped that one already)
#define ONE_WIRE_BUS 3 // Pin where dallase sensor is connected
#define MAX_ATTACHED_DS18B20 16You can also test my Ds18b20 code from here but you need to change from RFM69 radio to Nrf24l01+ radio,
https://github.com/sundberg84/HomeAutomation/blob/master/Sketches MySensors RFM69 radio/RFM_BeerCooler_Temp/RFM_BeerCooler_Temp.inoI would also try a bare pro mini + the temp sensor + resistor on a breadboard powered with 3.3v from ftdi adapter.
I also need you to doublecheck the resistance on that pull-up resistor:
Im having a hard time to see the exact colors but it that is Yellow, Brown, Gold, Gold that means you have a 4.1 ohm resistor to VCC which is pretty much a short and might have broken the temp sensor. Use a 10k or 56k.

@sundberg84 Coincidentally I yesterday had a FTDI powered 3v3 Pro-Mini hooked to a RJ11 socket to test and retrieve addresses using the OneWire.h from two plugged DS18B20 devices to add to those in the chain here already, the resistor was 4k7. The chain of now 12 devices also uses a 4k7 and continues to work flawlessly.
