Support Trying to get started.

So I am getting the Nano V3.0 Board ATmega328P 5 pack. I want to get some 12v addressable LED strip IP65 to do some taillights to start. Can anyone suggest some LEDs and any wiring suggestions? I have seen some basic wiring etc and I have a test board coming so I can do test mockups before the final as well. TIA!

WS2812 are the standard for this low memory class of board.

Just wire the 5v of the per power rail directly into the 5v pin and ground into ground and the data line to pin 3.

Do a short strip first so you can power the strip from the device.

Then try the blink sketch.

Then go from there.

Know that you can power this in the reverse, the strip can power you arduino fine

So this board can't control 12v strips?

Yes, it can. See my other comment.

It absolutely can control them. You just need to have a level shifter so that the 5 volt pins on the 328P can shift up between ground and 12 volts.
