I currently have a problem with a WS2812B led strip.
I think it's a physical problem because no matter what program I always have the same bug.
I have the beginning of my led strip which stays on.
More precisely, it lights up as long as no order is given.
When I give him the order to light an LED, this part will go out.
And as soon as my led made the order ask. The beginning part lights up.
Do you know what can cause this problem.
FYI: My power supply for my 54 LEDs is 5 V - 1.2A (I tried with more intensity, it didn't change anything)
I use the PIN 10 of an arduino mega for the control of the led (with a resistance of 330 Ohm in series (without this resistance i have the same problem))
The Gnds of my card and the LED power supply are connected.
Can you Help Me
Thank you very much
