Bridge<\/strong> Widget<\/strong> to \u015bwietne narz\u0119dzie do komunikacji mi\u0119dzy r\u00f3\u017cnymi urz\u0105dzeniami IoT w ramach projektu BLYNK. <\/p>\n\n\n\n

Pobiera on wirtualny pin (dowolny, kt\u00f3ry zadeklarujemy) i zamienia go w kana\u0142 do sterowania innym urz\u0105dzeniem. Oznacza to, \u017ce mo\u017cemy z jednej p\u0142ytki sterowa\u0107 dowolnymi cyfrowymi, analogowymi lub wirtualnymi pinami drugiej. Trzeba tylko zna\u0107 jej kod autentyczno\u015bci. Kody s\u0105 banalnie proste. Podobno to najrzadziej u\u017cywany widget. Nie mam poj\u0119cia dlaczego.<\/p>\n<\/div><\/div>\n\n\n\n
