c. SK6812 White & WWA
Ngati mukufuna kuyatsa koyera koyatsidwa, SK6812 white & WWA LED mizere ndizomwe mukufunikira. Chip cha SK6812IC chamtunduwu chili ndi tchipisi toyera ndi WWA. Izi zimalola kutentha kuziziritsa ma CCT osinthika mkati mwa mzere wa LED. WWA imapereka CCT kuyambira 3000K mpaka 6000K, kotero mudzakhala ndi kusinthasintha kokwanira kuti musinthe mtundu wowala kuti ugwirizane ndi malingaliro anu kapena zosowa zanu. Kupatula apo, kusiyanasiyana kumeneku kumapezeka mumitundu itatu ya kachulukidwe- 30, 60, ndi 144 makulidwe a LED. Choncho, ngati mukufuna kuunikira kamvekedwe ka mawu kapena kuwala kochepa, pitani ku mizere yotsika kwambiri ya SK6812. Ndipo komwe mukufuna kuwala kofananirako komanso kosalala, gulani imodzi yokhala ndi kachulukidwe kakang'ono ka LED.
Mtengo wa WS2812B
Mosiyana ndi SK6812, WS2812B ili ndi mitundu yosiyana ya RGB yokha. Apa simupeza zosankha za RGBW ndi WWA. Komabe, WS2812B imatha kupanga mamiliyoni amitundu yosiyanasiyana ndi RGB, koma ndiyocheperako kuposa SK6812. Apanso, kuyatsa koyera komwe kumapangidwa mu WS2812B sikuli koyera koyera. Apa, mtundu woyera umapangidwa mwa kusakaniza mitundu yofiira, yobiriwira, ndi yabuluu pamlingo wapamwamba. Zotsatira zake, zoyera m'mizere iyi sizikhala zoyera; m'malo mwake, khalani ndi kamvekedwe ka bluish. Koma ndi mizere ya SK6812 LED (RGBW), simudzakhala ndi izi. Ili ndi njira yoyera yomwe imabweretsa kuwala koyera komanso koyera.
2. Kusiyana kwa Ntchito
Chithunzi cha SK6812
Mizere ya LED ya SK6812 imagwiritsidwa ntchito pomwe mukufuna zovuta zambiri komanso zosintha zamitundu. Izi ndizabwino pazowonetsa zowoneka bwino, zowonetsa zamalonda ndi zotsatsa, zisudzo ndi kuyatsa siteji, etc. Kupatula apo, mizere ya LED ya SK6812 yoyera & WWA ndiyabwino kwambiri pakuwunikira nyumba komanso kuchereza alendo.
Kugwiritsa ntchito WS2812B
Popeza WS2812B ndiyotsika mtengo poyerekeza ndi SK6812 LED, mutha kuzigwiritsa ntchito pa DIY ndi mapulojekiti owunikira ndi bajeti yotsika. Zokonza izi zimagwiritsidwa ntchito kwambiri pokongoletsa nyumba, zochitika ndi kuyatsa maphwando, zowonetsera zotsika kwambiri, masewera ndi kuyatsa makompyuta, ndi zina zotero. Kupatula apo, ngati mukufuna kuyatsa muzovala zamakono monga zovala, zipangizo, ndi zina zotero, WS2812B ndiye sankhani yoyenera. .
3. Kuvuta kwa Mapulogalamu
SK6812 Programming Complexity
Malaibulale amathandizira bwino SK6812, komabe ndizovuta kwambiri kupanga pulogalamu kuposa WS2812B chifukwa chokhala ndi njira zowonjezera. Komabe, simudzakumana ndi zovuta kugwiritsa ntchito laibulale yoyenera ndi kuphatikiza.
WS2812B Programming Complexity
