Hi Bryant.
To control the LEDs you use PWM to change their color.
Unfortunately, we don’t have any tutorial explaining how it works using LUA programming language.
We have some tutorials that explain this concepts using arduino IDE:https://randomnerdtutorials.com/esp32-esp8266-rgb-led-strip-web-server/
How RGB LEDs work: https://randomnerdtutorials.com/electronics-basics-how-do-rgb-leds-work/
I hope this helps.

Sara

Gave it a try today and after some trial and error, got it working. Unfortunately I had a bad MCU, but once I realized that, it went pretty smoothly.

I am a newbie and was wondering if you have further information on how I can adjust the colors. Not sure my LEDs are the best quality and did find the red connection was swapped with the green, but thought maybe there is a way to play around with the settings.

Thanks much for all you all offer – Bryant

Hi Carlos.
Yes, but you have to measure current consumption and see if those transistors are appropriate.

Hi,

If I want to do more than one meter of led strip would this schematic work?

I am always learning from you and I am very thankful for all your posts. I am trying to transform a single 10W rgb led lamp to be controlled via wi-fi. The led board has 3 wires, one for VCC, one for GND, and one for signal. Do you have a graphic on how could I connect it to an ESP8266? As always, thank you in advance.

Hi.
The OUT- should be connected to the ESP8266 GND. And the and IN- should be connected to GND of your power source.

That step down converter has IN+, IN-, OUT+ and OUT-, but you only need to connect one cable to the esp and one to the power source. Should they be connected to IN+ and OUT- or how does that work?

In reply to Jan Herkner. The same values should work with 24V... The ESP will output only 3.3V regardless, so the PWM signals is always the same.

first of all nice project.
What do i need to modify to run the same with 24V?
What are those values and where you get them from?
pwm.setup(5, 1000, 1023)
pwm.setup(6, 1000, 1023)
pwm.setup(7, 1000, 1023)

Hi.
It might be something wrong with your LED strip, or it is not fully compatible with this tutorial.
