I am currently on a Uno and using the fastled library. Trying to find a simple method of converting the Arduino output to the 12V supply an using that to branch off to my 2 separate LED strings with their own 5V regulators.
I'm lost here already. The WS2812 chip expects a 3.3volt or 5volt datastream.
12volt data will fry the first LED.
Or are you trying to power the strip with that 2N3906.
The 2N3906 is a small-signal transistor. It can't power a LED strip.
AFAIK there are 5volt and 12volt digital strips.
Digital strips expect a constant 5volt or 12volt supply on the strip with a current capability of ~60mA per LED.
The datastream controls the LEDs.
Post a link to the LED strip.
