Customer:
I’m not sure how to connect the WS2812B LED modules. Each module has 6 contacts on the back: two labeled GND, two labeled D, and two labeled VCC. I’ve tried various combinations connecting VCC and GND to the Arduino board, but nothing happens. I also tried the circuit diagram in the documentation, but the GitHub documentation raises more questions than it answers. How should the module be connected to make it light up?

Dobar dan,
javljam se u vezi LED WS2812B modula, ne znam kako ih treba povezati.
Svaki modul ima na stražnjoj strani 6 kontakata od kojih su dva označena sa GND, dva sa D i dva sa VCC. Spajajući na Arduino, pokušao sam svaku kombinaciju VCC i GND spojiti na pločicu, ali ništa se ne događa. Shemu na slici u priloženim dokumentima sam također isprobao, a dokumentacija na Githubu ostavlja više pitanja nego odgovora.
Kako bi se modul trebao spojiti da svijetli?

Soldered Support:
Connect the power supply to the VCC pin of the module (connect Arduino 5V pin to the VCC pin of the LED module). Connect GND to GND. For the D pin, select one digital pin on the Arduino board. For example, use digital pin D6 and connect it to the D pin of the module. These are smart LEDs and need to be programmed to light up. When connected to power, they won’t turn on until they’re programmed. You can use the library from our GitHub for programming.
It’s important to pay attention to how you connect the module because it has Din and Dout pins—you need to connect the microcontroller’s digital pin to DIN. For connection details, send a picture of the module you have. If you have problems with programming, feel free to reach out.

Napajanje spajate na VCC pin modula (s Arduino 5V pina na VCC pin LED modula). GND spojite na GND. Za D pin trebate odabrati jedan digitalni pin na Arduino pločici. Uzmete npr. digitalni pin D6 i spojite ga na D pin modula. Kako su ovo pametne LED diode treba ih isprogramirati da bi svijetlile. Kada se spoje na napajanje neće se upaliti dok se ne isprogramiraju. Za programiranje možete koristiti library koji je na našem GitHubu.
Važno je da pazite kako se spaja modul jer ima Din i DOUT pin te vi trebate digitalni pin mikrokontrolera spojiti na DIN. Za detalje oko spajanja pošaljite sliku modula koji imate. također ako ima problema s programiranjem slobodno se javite.
