O simpla statie meteo cu display OLED

Va salut ! Actualizez blogul cu o simpla "statie meteo" (denumire cam pompoasa...), creata cu un Wemos D1 mini (da, am multe montaje cu aceasta mica bijuterie !) si un display OLED SH1106. Datele meteo sunt furnizate de OpenWeather. Necesita imbunatatiri (ora automata vara/iarna), dar este un punct de plecare pentru cine vrea sa experimenteze. Succes !!
