Iyi protocol inozivikanwa pasi rose ichawedzera kuchinjika mukubatanidza chigadziriso chako nemidziyo yechitatu-bato. Kunze kwezvo, muDMX512, masaini anogadziriswa mitsetse anotumirwa zvakafanana. Saka, kana imwe LED yaparara, imwe yacho haizokanganisa kushanda kwayo. Iwo akanakira theatre, nhanho, konzati, chiitiko, kuratidzwa, firimu, uye kugadzirwa kwemwenje.
Nekudaro, tenga SPI inogadziriswa LED mitsetse kana iwe uchida kunyatso kudzora pamusoro pe LEDs. Ivo vanokutendera iwe kudzora kupenya kwemavara uye mhedzisiro yeimwe yega LED strip paPCB. Izvi zvinoita kuti ive yakanakira kudhijitari signage, TV & yekutarisa kubatanidzwa, inopindirana art mwenje, nezvimwe. Iyo yakapfava uye inokurumidza kuseta inoenderera mberi ichivaita kuti vakwanise DIY mapurojekiti.
Chero chipi chaunosarudza pakati DMX512 uye SPI inogadziriswa LED mitsetse, LEDYi ndiyo yako yekupedzisira LED strip mutengesi. Isu tinokupa iwe yekugadziridza nzvimbo kune ese ari maviri akasiyana. Tinogona kupa inogadziriswa ma LED mitsetse ne IP52 (silicone coating), IP65 (silicone chubhu), IP65H (kupisa shrink chubhu), IP67 (silicone kuzadza), IP67E (silicone extrusion), IP68 (PU yakavharirwa) kana chero chinhu sezvaunoda. Isu tinopawo zvigadziriso zvezvivakwa izvi 'voltage, mashandisiro emagetsi, dimension, chimiro, kureba, uye kurongedza. Saka, kumirirei zvakare? Bata nesu ASAP!
