Powering roughly 3 5m addressable rolls and neopixel halos

by Dirtydev393 on Sun Jan 06, 2019 9:58 pm

I do vehicle lighting, like wheel lights and underglow and custom headlights with halos, and i have been using regular 5050 SMD RGB strips. Lately i have been buying 12v and 5v addressable LED strips and the 5v neo pixels. I have to main questions.

1. is there a way to make addressable 5v and 12v strips work together (ws2812b and ws2811)? i use bluetooth sp105E and sp110E controllers mostly, when using 5v i use a 10/20a 12v to 5v buck converter.

2. i want to power all the strips on my truck without having leds fade or any issues due to having so many lights, would that be a voltage issue running all that length in LEDs, or an issue with the power on the data wire? i have a signal repeater i will link below. When would the repeater be necessary? I also wanted to wire it where every strip is in series so it literally flows around the vehicle, instead off each wheel having all 4 inputs tied together and the strips doing the exact same thing, will that be an issue with using the repeater trying to have them in series? since the repeater has only one input and multiple outs?

I wanted to use 12v strips for my wheels because i found some triple row strips that would be very bright and i wanted to use the 5v neopixel halos in the headlights and in the fog lights. I know some controllers are linkable where each led strip has its own controller but in the bluetooth app you can lock them together, would that the only way to make 5 and 12v work together?

Using these lights in a 12v auto setting is all ive used them for i havent played with anything else that like adruino or anything like that so im new to all this.

If you have any questions on Adafruit products feel free to ask but we can't comment on other products we do not sell. The fading is probably caused by power as the data line is low current and more susceptible to noise than power droop.

the neo pixel 5v halos are your products?

What is your question about the "halos" (do you mean rings ?)

how to use the 5v "rings" or strips with 12v strips AND when would a repeater be needed.

I believe i found a thread saying the data is still 5v on the 12v strip, just run +12v to the strip and the data wire, and take the 12v - from the strip and hook it to the - off my controller that will be 5v and it would work since 5v and 12v both still use 5v data. Was wondering if you could add to that or possibly confirm or deny?

if i add power cable every meter or so on the strips that should prevent dimming and discolor correct? so when would the repeater/amplifier i have be necessary?

Power every meter should keep fading to a minimum. Neopixels work best if the data has no more than a meter between pixels or controller in ideal conditions. Noisy environments will decrease this.

so if i do have greater than a meter on the data wire between strips or pixels i would need the repeater to boost that correct? also if i wanted to wire everything in series (data in to data out all the way down) i would need an amp for every long data run greater than a meter if wired in series because the amp only has one input and multiple outs?

If you have a longer gap you would benefit from a repeater which could be another pixel or some other form. We do not have repeaters so you would have to ask the maker of that unit.

okay thank you, i have one more question, i did get the 5v and 12v strip to work together however the blue and green colors for each strip are opposite. If i pick blue the 5v strip may be green while the 12v is blue or vice versa, the same if i pick green, if i chose red BOTH strips are red though. Is there a way to correct that? i will upload my diagram, its very poor haha.

Different strips can have different orders of the colors in the pixels themselves. In order to get the same color you would need to use two controllers or two pins on an Arduino or Adafruit microcontroller.

where could i find a diagram for such? ive never had an arduino i dont know where to begin.

Look at the learning system at learn.adafruit.com.

Thank you for all your help! Looking forward to playing with the system, i already have a raspberry pi i could possibly use.
