I have 12v addressable LED lights, the inputs are Positive, Ground and a single Data line.
I’ve also got my hands on the Athom LED strip controller, that I want to use to run these lights. I believe this has WLED pre-flashed. The outputs are W, G, B, R and VCC.
I have a pretty basic question, how do I connect the Athom controller outputs to my LED lights?
How do I get the RGBW outputs to be multiplexed into my data line?
And how is the Ground connection supposed to be made? Do I ground directly with my power supply or is there a particular terminal?
Well, setting it up is quite easy.
As labeled on the controller there are terminals called „VCC, R, G, B and W“, that meant the VCC Terminal is your positive voltage (strip may labeled +12V or any other common voltage ratings)
You go to „Settings" then „LED preferences" > Here you can change your LED type to Analog RGBW
As mentioned at the beginning: VCC is your positive voltage terminal. That means by either pulling R, G, B or W to GND this color with light up. That’s because the Strip uses PWM switching to GND

If colors not match, try messing around with those GPIOs by switching GPIOs if needed!
Gotcha, yep I think I got the wrong types, i.e. my controller and LEDs don’t match with each other.
I’ll pick up another one or try to connect to my existing QuinLED controller, the main thing is that there is a large distance between the front of the home where the existing controller is setup and the back of the house where I want to set up the remainder of the lights.
