Hi,
To solve a problem with a short white flash of LED strip when powering on (Caused by the boot state)
I want to make some kind of delay between the positive power of the LED strip and poweradapter.
Made some drawing:
But I don’t know how to offer a delayed signal to the Yellow Wire.
Who knows?
As I stated in the original post on this issue, an RC circuit, with a resistor and capacitor, like this: https://www.build-electronic-circuits.com/rc-delay-element/
If you want a commercial product, it costs more, but will work better. Try this configurable board as a starting point:

Thanks huggy,
As I just referred to your reply in the original post, RC circuit did not work.
Thank you for the time you spent finding a commercial product.
I really appreciate that.
For those who didn’t follow the original post and only got here through the Hardware section:
Think I solved the problem with 555 Timer delay
So my first drawing becomes something like:
I just tested it on a breadboard with an SRD-05 relay on pin 3 of the 555 timer (instead of a single LED) and the delay worked.
Tomorrow I will actually try it on my LED strip.
For now a 
to celebrate.
