Ws2811 strip from govee with arduino

Using Arduino LEDs and Multiplexing
1

Hello folks!

I bought a ws2811 (segmented control, 5 leds on 1 ws2811 chip) led strip from govee and have successfully controlled it several times with my Arduino and the Fastled library. For a larger project I have now bought the 20m set from Govee, consisting of 2x10 meter led strips (24v). I was able to control one of the two strips as usual with my arduino, but not the other. I can rule out hardware errors. Does anyone have any idea what could have happened? Both strips work with the supplied Goove LED controller.

Amazon Link to strip

For anyone asking: I bought the Govee strips so that I already have a suitable power supply unit with me and can control the strips with the supplied controller and app after the project has been completed.

I have also verified that the chips are actually ws2811 and tried to mix ground and data.

Maybe the chinese supplier has used two types of strips in one set and implemented the different protocolls in their controller code and I just dont have this information…

#include <FastLED.h>

#define LED_PIN 6         // Pin für den LED-Streifen
#define NUM_LEDS 1        // Anzahl der LEDs

CRGB leds[NUM_LEDS];      // Array für LED-Farben

void setup() {
  FastLED.addLeds<WS2811, LED_PIN, RGB>(leds, NUM_LEDS);
}

void loop() {
  leds[0] = CRGB::Red;
  FastLED.show();
  delay(1000);

  leds[0] = CRGB::Green;
  FastLED.show();
  delay(1000);

  leds[0] = CRGB::Blue;
  FastLED.show();
  delay(1000);
}

Did you mind the data direction, usually shown with a silkscreen arrow.

Yes, it is marked as DIN and DOUT.

Hi,
Have you got the gnd of the strip supply connected to the gnd of the controller?

Hi,
thanks for your input. As I wrote above, one LED strip is working just fine with the exact same setup. And yes, I also connected my arduino to ground, otherwise nothing would work.

Hi,
Can you please post some pictures of your project connected?
So we can see your component layout.

Thanks.. Tom... :grinning: :+1: :coffee: :australia:

Yes, I have attached some. If I connect this datapin to the same type of led strip from the exact same set of govee (and connect ground) nothing works… maybe the chinese have used two types of strips and implemented the different protocolls in their controller and I just dont have the information…
