Qhov kev qhia no yuav qhia koj qee qhov pib ntawm kev siv Sparkfun RGB Led WS2812B nrog Arduino UNO

Kauj ruam 1: Taw qhia

Nqe lus piav qhia:

Nov yog pawg thawj coj tawm rau WS2812B RGB LED. WS2812B (lossis "NeoPixel") yeej yog RGB LED nrog WS2811 ua rau sab xis rau hauv LED! Txhua qhov tsim nyog pins tau tawg mus rau 0.1 "spaced headers rau cov mov ci yooj yim.

Kev qhia tshwj xeeb:

1. Loj: 50mm x 50 mm2. Xim xim: Liab, Ntsuab, Xiav

3. Saib lub kaum sab xis: 120 degrees

4. Liab: (620-630nm) @ 550-700mcd

5. Ntsuab: (515-530nm) @ 1100-1400mcd

6. Xaj: (465-475nm) @ 200-400mcd

7. Qhov piav qhia:

VCC - Cov tswv yim hluav taws xob 5V

GND - Ib qho, hauv av, 0V siv cov khoom siv hluav taws xob.

DI - Cov ntaub ntawv los ntawm microcontroller los rau hauv tus pin no.

DO - Cov ntaub ntawv raug hloov pauv ntawm tus pin no, kom txuas nrog cov tswv yim ntawm lwm lub pixel lossis sab laug yog tias nws yog qhov txuas kawg hauv cov saw.
