Wawa:
Post a real picture of the setup, not a Fritzing mess.The Fritzing can't work like that, because you haven't powered the Arduino,
and didn't connect sensor ground to Arduino ground.
There are no 5volt batteries either.
Leo..
This isn't Fritzing. It's Paint. I didn't post a real picture because this circuitry is buried under a ton of electronic packaging that would be a pain to take out. But it's a pretty simple layout.
Arduino is powered via USB.
5 volt battery is a Anker 13000. They in fact do exist.
Are you saying I should connect sensor ground to only the Arduino?
