That question clearly doesn't belong here. There are several problems with it on EE.SE:
- It is a high level user issue, not really about electronics. The OP is at the level of connecting a bluetooth block and a arduino block. If you can't draw a schematic from the question, just a block diagram, then it's probably off topic.
- There is no evidence the OP is interested in or wants to actually understand the electronics. This is simply make it work for me, the electronics equivalent of giv me da codz.
As a aside, this is really why most arduino questions don't belong here. It's not the arduino that makes them off topic specifically, but that those asking arduino questions are likely to not be interested in the electronics.
- Much very basic, and what should be obvious, information is missing. The only symptom is "didn't work" and that certain pins "aren't working". Not only that, we have no idea what those pins are, or even which component of the block diagram they belong to. Perhaps some of this would be implied context on a arduino site, but certainly not here.
- The writing, while still decipherable, isn't doing the post any favors. This isn't a reason to close on its own, but it does add a little annoyance, which would tip it over the edge if someone is right at the cusp of deciding about downvoting or closing. We get a lot worse than this regularly, and this isn't all that bad. But, presentation matters, a lot. Never understimate how sloppy presentation is a slap in the face of anyone you present to, especially when you are asking for a favor.
This post was correctly closed here. Therefore migrating it to arduino.SE with the permission of the mods there was a reasonable action.
