NeoPixel + Blynk (ZeRGBa)= Custom RGB Lighting for your PC?

I had this Idea a while ago. I need help on how to implement it. It would be pretty basic, but I want it to be more “Awesome”.

Also, I would like to know if someone actually did it irl :slight_smile:

I making similar project right now, pm me here.

Okay, Tell me When you finish it. I might not have the time to make it.

Click here to see my own Blynk LED project using common ws2811/ws2812/ws2812b leds.
Code is in there too… but just for you, ill post the latest version here along with the dash QR code.
It will be about 3500 energy to clone it.

Well… I don’t have 3500 energy, but if I edit that code, I can make it work with only one ZeRGBa, Right?

I’ll upload it to instructable and arduino project hub when I make it, Hope I get 2000 energy or so.

Not easily no. Just use a slider to pick the colour. Far easier (and cheaper).

Huh? I thought using the ZeRGBa would be more cheaper since it uses only 600 energy, and its far more advanced i think.
AFAIK the ZeRGBa’s a HSV selector to RGB widget.

I haven’t used an ESP8266 with Blynk, Maybe I’ll try if I get a WeMos or ESP-12 or so.

I copied your project.
But after each action writes “Your NodeMCU was disconnected”.
What am I doing wrong?

Have you had success getting your hardware connected via an example first?
Also check you’re not flossing the cloud server as I use a local server with no flood limits

Yes, I used the library Adafruit_NeoPixel.h.
With this library LEDs work.
But with FastLED.h LEDs do not light up.
I’m using WS2812 16led
I use the cloud server.

If you’re not using my code and the fastled library then I can’t really help as you’ll need to rewrite your own code with the changes.

Also when using the cloud server make sure you have send on release turned off for the slider widgets else you will cause a flood error and be disconnected.

I use this code:

If
#define DATA_PIN 12
What do I get…


If
#define DATA_PIN 2
That project is compiled, but the LEDs are off

on?

Go and copy the code again because you loads of strange characters in there which is causing your error.

And yup costas good spitting. Turn of off :slight_smile:

I connected ws2812 to pin D6(GPIO12) and have #define DATA PIN 12


Therefore, it does not work.
Changed #define DATA PIN 6 and it worked.
Thank you!
Have a nice day

That’s so weird! Might be hardware dependant on how you define pins.
Esp8266/nodemcu define digital pins as gpios

i use your code but get some error
