Thanks , but, I followed the destructions from this:

https://www.youtube.com/watch?v=ZC_sEW3_694

Start watching from 24.22 minutes. This where he says what to wire upto
which pins on the PiZero board, and the pin 2 is definitely 5v. Well
that is what it says it is.

Regarding 0v between motion pin and the 5v pin, means that I just
checked that, and maybe I shouldn't have done that.
The video will make it more clear I hope.
