Hello everybody, I have problem with Led RGB neopixel strip (WS2812B chip). I'm using 45 leds and I'm controlling it by Arduino Nano. Power supply is USB charger 5V/3A ( 45 x 60mA = 2,7A ). Led strip and Arduino have same ground from USB charger. If I use any arduino script (lib: FastLED, or NeoPixel) for animation on script, 'all' working good. Good is all single color and low brightness color. If is high brightness or white color (255, 255, 255) all strip flashing with random color in random pattern.
I try study and testing it and I find out: I testing only 3 diods. Differend color on all diods work good, but if I set (255, 255, 255) on first diod -> first was white and second and thirs are random flashing ..... If I set on first diod only one color (255, 0, 0) or low grightness color (32, 54, 10) and on second diod I set white color -> first and second diods was good, and third diod flashing (sometimes flashing with correct color, sometime random color). If I using for supply 3 diods only Arduino (without USB charger) all work good. But all strip can't supply by arduino.
My knowledge is: all diods after one high brightness are flashing. And I think, It look as bad grounding, but I don't know why because I have connected same ground to strip and arduino.
If somebody can help me I will very happy. Thanks
