Need help making a lotion activated led strip

Hello, I am trying to make a cuttable led strip that runs off of 12v be motion activated by a pir sensor that runs off 5v. I am using a 12v wall adapter and running power straight to the arduino. I am then powering the board through the vin or Voc pin then I have power running to a nte 960, a 3 terminal positive voltage regulator with a max 35v input and 5v out connected to my pir sensor. I have no resistors or diodes or anything else. Am I on the right track here?

I second that e-lotion!

Draw a picture. It will be much easier to see the circuit you're asking about that way.

Haha, I clicked on this thread just because it had "lotion" in the title!
