RGB LED - Light Show Drone with pixhawk 4


First and foremost, I am very new to this so, please, bare with me.

I’m trying to create a light show drone. Have found a solution for pretty much everything I need (hardware wise), but I’m still lacking a solution to control the LEDs. actually, I’m struggling to understand how will the Pixhawk 4 communicate with the LEDs. Do I need a LED controller?

The purpose is to program the LED’s to, at a certain moment in time, be in a specific colour at a specific brightness level.

I would be very grateful if someone could shine some light on this subject.

Thanks in advance.
