Hello, I have a 12V multiple color LED strip and I'm wondering if it is possible to controll the color and brightness via Mobiflight?

#

what exact type of the led strip it is?

#

Is it with addressable or non-addressable leds?

#

There is a way but it requires some extra wiring and mosfet/mosfets

How do I know that?

somber lava How do I know that?

How do you currently control the color and brightness of this strip?

gentle oyster How do you currently control the color and brightness of this strip?

Using a controller

Please, take a look at the link I gave you above. It will help you identify what kind of rgb strip you have. This way it will be easier for us to help you.
Eventually, give us a link to the product page from the store you bought it from

#

without giving any details/specification of the product, it's hard to provide help.

This is how the strip looks like

#

The pins on the strip are R, G, B and +12V

#

Standard common anode 12V strip. You need three power mosfets and 3 PWM outputs. It's not really color/brightness, more like red/green/blue intensity, but MF can handle that.

#

For the common IRF520 boards shown on https://docs.mobiflight.com/devices/mosfet/, wire VIN/GND of all breakouts to a shared 12V power supply. On the strip, connect +12V to V+ on one of the breakouts, and the red/green/blue lines to a V- each

So each Mosfet for R, G and B, right?

Yes

One R mosfet, one G mosfet, one B mosfet. Each with their own arduino pin, sharing vin and gnd

So only non-power pins are SIG pins and they are connected to three PWM pins?

yes, to control brightness of each color channel.

#

256x256x256=16.8 million possible colors.

gentle oyster 256x256x256=16.8 million possible colors.

That's a theory.
From my own tests those rgb strips are terrible in replicating colors and the range is very limited.

proven lichen Nov 17, 2025, 6:26 PM

#

I mean, it is still 16 million colors, just not the 16 million you might expect

gentle oyster Nov 17, 2025, 6:44 PM

#

Yeah, I guess the limitation is in perceived differences between colors, especially at the higher end of the PWM range.
