I recently purchased a replica flux capacitor online with the intention of putting it in my car and using a USB port in the back to power it.
I was happy to learn that the plug it uses for the LED fading lights is a simple AC-DC one with ratings of
4.2V +/- 0.6V and 550mA
It has a handy 2 pin connector to go off to the LED strips so I feel all I need is a USB cable with a potentiometer in series with the positive side and I set it to a value where they light up.
However I'm a complete Electronic novice and racking my brain watching YouTube videos on the subject involving resisters in different combinations and there are a lot of potentiometers to choose from with different ratings.
If I could get some clarification that'd be great as I feel I'm oversimplifying the problem.
