Customer:

Which pin is the WS2812B LED connected to? I want to control this part of the circuit, turning it on and off as needed. Unfortunately I haven’t been able to get control over it. I tried to detect which pin it’s connected to by defining the pin in code and then using digitalWrite to turn it off. Clearly it’s not that straightforward. I looked at the documentation but couldn’t find the answer.

Poštovani, molim vas javite na koji pin je spojena WS2812B LED-ica. Naime zelio bi imati kontrolu nad tim djelom sklopa, paliti i basiti ovisno o potrebi. Na žalost nisam uspio dobiti kontrolu. Isprobao sam detektirati na koji pin je vezana pomocu lasicnog načina da definiram pin i onda putem digitalwrite naredbe basim port. Očito to nije tako trivijalno. Pogledao sam dokumentaciju no nisam uspio nači odgovor tj isti ne znam iscitati .

Soldered Support:

This is a WS2812B LED and you cannot control it with digitalWrite(). You need to use the FastLED or NeoPixel library to control these types of LEDs. You can look at one of the examples and simply apply the pin it is connected to (D8) and set it to have one LED. It’s not trivial, but it’s not too complicated either.

To je WS2812B ledica i ne možete ju kontrolirati pomoću digitalWrite(); Morate koristiti FastLED ili NeoPixel library za upravljanje takvim ledicama. Možete pogledati jedan od primjera i samo primijeniti pin na koji je spojena WSica (D8) i staviti da imate jednu ledicu. Nije baš trivijalno, ali nije ni previše komplicirano :grinning_face:
