Reply To: Two ESP8266 P2P with WS2812b

Hans Hans Hans,

I don’t know what to say  Thank you Thank you Thank you

It works

What was missing was this: int buttonState=0;
What I have changed:
buttonState=digitalRead(SWITCH); instead of (button)
and
pinMode(SWITCH, INPUT_PULLUP); instead of pinMode(button, INPUT); 

Now I will try it with the Transmitter
