Librarie si driver

Folositi chat gpt si descarcati driverul necesar mai intai care(ceva universal driver) si ceea ce aveti nevoie in platform.io de la libraria ada, troyka library nu a functionat pentru mine, dadea temperaturi doar de 0(daca folositi vscode, mie in arduino id cloud nu mi a recunoscut portul). A durat o seara intreaga sa mi dau seama, poate va salva si voua ore bune

Librarie

La mine a mers cu libraria TroykaDHT.
Cu cea de la Adafruit si SDHT nu a vrut sa functioneze.

PULL LOW to start (SimpleDHT)

Nu functioneaza cu PULL LOW 1 ms din SimpleDHT.cpp linia 311. Aceasta linie trebuie inlocuita cu delay(10); // un delay de 10 ms iar senzorul va functiona.
