hi

so im building my own wheel and im gonna use neo pixels for rev and flag lights so one row of 15 and 2 rows of 3

do i connect them all together ? or in 2 groups? flag and rev?

also how much mA will those neo pixels use…. i like to connect them all to the same pin becease i almost come short of pins on my mega

Hi ! They must be daisy chained, simhub has only one output per Arduino board.  You can read how to wire them here : https://github.com/SHWotever/SimHub/wiki/Arduino-WS2812b-RGBLEDS--Wiring-Setup  

Neo pixels uses 20ma per led max so much lower in real conditions as it's almost never white nor full brightness.

Thx allot dude... gonna be a complicated project, but they definitely need to be connected onto 5v

I’m planning on using power from wall socket to my Arduino.... I keep reading forums and the one says I’m able to do only 500 mA with Arduino the other one then says you can do up to 1A so what’s true ?

If you go through the barrel plug you will be limited by the 5v 500ma regulator indeed , you can simply power the various devices using the power plug 5v as described here https://github.com/SHWotever/SimHub/wiki/Arduino--Setup#powering-considerations
