Walczę o d kilku/kilkunastu dni z czujnikami temperatury DS18B20. Mam ich 10 szt gdyż chcę nimi mierzyć temperaturę przy piecu: Piec, wyjście na grzejniki, powrót, wyjście na bojler, powrót, podłogówka itp. itd. Mam jednak problem z wyświetlaniem temperatury, a mianowicie przy wgraniu programu czy do NodeMcu, czy do Arduino Mega temperatura sie nie pokazuje. Dopiero po odcięciu zasilania do czujnika "zaskakuje pomiar" i po ponownym podłączeniu zasilania już jest ok. Co może być tego przyczyną. Nie chcę biegać do Arduino za każdym zanikiem napięcia w sieci. Może nowa wersja Clouda coś nie tak współgra z Arduino?
Dla Arduino Mega pokazuje cały czas 5 stopni a dla NodeMcu nic.
Bardzo mało jest informacji na temat programowania przez ArduinoIDE - Może ktoś obcykany by zrobił jakiegoś tutoriala?
Moj program z Arduino Mega
