First answer - DON’T.
Not until you know WHAT you’re doing and WHY.

Draw out and list as much detail as you can, then we’ll ask more questions.

Good answer! :face_with_raised_eyebrow:

The project that i am working on is a textile scanner.

I have 8 led strips that turnes on and off individually and take a picture with an iPhone each time a led strip is turned on.

Led strips that i using is 12v and the ac adapter that powers all eight led strips is this ac adapter.

But the bluetooth camera shutter that i am using have it’s own battery and i would like both ledstrip and remote to use same power supply.
