@Giorgio_Salmi Good day sir! Can i ask for your code? i have very similar project with you that controlling led strips using esp8266. my problem is that there is delay to the respond of the leds. My thesis project is a basketball shotclock and time is very critical. Sir i need your help please thank you 
here is the code of the receiver esp8266

uint8_t pps = 4; // number of Pixels Per Segment
CHSV segON10(96, 255, 255); // color of 10s digit segments NOT TURNED RED
CHSV segON(96, 255, 255); // color of 1s digit segments
CRGBArray<NUM_LEDS> leds; /* CRGB leds[NUM_LEDS]; ← not using this. Using CRGBArray instead. */
// Name segments (based on layout in link above) and define pixel ranges.
CRGBSet segA( leds(pps * 0, pps - 1+(pps * 0) ));
CRGBSet segB( leds(pps * 1, pps - 1+(pps * 1) ));
