How to check my soldering using a multimeter
-
Again: thanks for the fast replies. Don't guys to work or something? :P
- Connecting the GND to the FTDI made my monitor work again
- Using the multimeter I see the radio gets 3.3 V, so I guess the problem is somewhere in the data pins.
- @scalz Thanks for the link! I was looking for something like that. I'm gonna read it and I'll return with some questions, or answers ;)
@Maurice-Krijtenberg - With that info - your conclusion is most likely true. If you are getting a good voltage but Radio Init fail - recheck every data cable connection and solderpoint.

Finally!! I got it to work :)
Using "Continuity mode" on my multimeter, I found out that two connections didn't work. I probably damaged my board during soldering. Using two wires I was able to get it working
One step closer! Thanks again @sundberg84 and @scalz

@Maurice-Krijtenberg - nice to see! Great work.
This is why its so dangerous... you get that rush when you fix something and you need more and more... its like a drug :)
Thanks for reporting back! -
Hello, now you have read how to use your multimeter, may I suggest you check more tutorials from Spzrkfun website ? I think they have one about basics of soldering that you should watch ;)
Looking at the "balls" of solder on the pins of your Arduino you skipped that step which is crucial to have good working circuits.
And don't forget to always keep your soldering tip shiny ! -
Hey @Nca78
Thanks for the suggestion... I just watched this video from sparkfun: https://www.youtube.com/watch?v=f95i88OSWB4
Wow.... I was doing it soooo wrong haha. I'm gonna practice a bit to get my "balls" look more like "volcanos" (yes, still talking about electronics :P ) -

First time I've seen a person using safety goggles when soldering, and I've been in the industry since early 90's.. Working in a handful different factories.

haha :joy: well, to be extra careful, I wear gloves during soldering.

Another thing I noticed in that video..
"Some has a heating element in the handle, this one has it separate" So the heating element is in the blue box?? And heat is transmitted through the wire to the handle? Won't you burn your pretty hands, if the heating element was in that blue box, Wonder how hot that cable would be, to heat the soldering iron part to 300 degrees celcius..
Why don't they make those tutorials factual correct?
