Dasduino purple LED on D8 stopped working after code upload

Customer:

I received a Dasduino beginner set. On first power-up, the LED connected to pin D8 was fading in and out with a purple color. After uploading my first program, the fade effect stopped and it just stayed lit (as expected, since the code was replaced). However, the next day the LED stopped working entirely. No matter what I send to pin D8, it has no effect. Is it possible the LED burned out, or am I sending the signals incorrectly?

Original message (Croatian)

nedavno sam kod vas naručio Dasduino set za početnike. Kod prvog uključivanja je na njemu LED dioda spojena na D8 svijetlila ljubičasto fade-in/fade-out. Nakon uploada prvog programa je prestao fade-in efekt, i samo je svijetlila (očekivano, jer je kod prebrisan). Međutim, dan poslije ta LED-ica uopće ne svijetli, i što god da pošaljem na pin D8 nema efekta. Je li moguće da je pregorila, ili krivo šaljem signale na nju.

Ako postoji online dokumentacija za ovo ili neki FAQ koji mi je promakao, slobodno proslijedite.

Hvala i lp

Soldered Support:

To control the LED, check the examples in the Arduino IDE under File > Examples > Examples for Dasduino Core > WS2812 Built-in library. You can see how to control the LED using the WS2812 object. This should work correctly.

za upravljanje LE-diodom pogledaj example-ove koji se nalaze u Arduinu pod File>Examples>Examples for Dasduino Core>WS2812 Built-in library, evo screenshota:

Možeš vidjeti kako se LED-icom upravlja preko WS2812 objekta. Ovo bi trebalo raditi OK, javi rezultate testiranja.

That’s it, it works with WS2812! Thanks for the guidance, I’ll keep experimenting with the library.

To je to, radi sa WS2812! Hvala na uputi, dalje ću se igrati s tim libom :slight_smile:
