Selamun aleykum hayirli gunler dilerim
Bana Arduino kodlariyla ilgili yardimci olabilecek arkadaslara onceden tesekkur ederim.
yapmak istedigim sey xiaomi oda termometresi uzerinden bluetooth kullanilarak esp 32 kartima sicaklik,nem ve batarya degerlerini alip yorumluyacak ve bu degerleri lcd ekrana yazdirmamda yardima ihtiyacim var.
durum soyleki hersey tamam degerleri aliyorum ve seriport ekranindan oda sicakligi nem ve batarya degerini okuyabiliyorum sadece bu okunan degerleri bi turlu lcd ekrana yazdiramadim,yeni oldugum icin neyi nerde nasil kullanacagimi bilemedim heralde ondan dolayi isin icinden cikamadim,bu yonde deneyimli veya bilgisi dahilinde olan arkadaslardan yardimci olmalarini rica ediyorum,onceden tesekkurler.
kullandigim kodlari asagida paylasiyorum.
