Arduinoda Namlik va Harorat datchigini takomillashtirish

DTH11 datchigi yordamida xona haroratini boshqaradigan qurilma qilish .

Ishlash printsipi: DTH11 datchigi xona haroratini aniqlaydi va displeyga yuboradi belgilangan gradusga qarab 5V DC FAN qurilmasi ishga tushadi.
Arduino bilan LCD ulanishi LCD to'g'ridan-to'g'ri Arduino-ga ulangan . LCD-RS, EN, D4, D5, D6 va D7 pinlarini Arduino-ning 7, 6, 5, 4, 3 va 2 raqamli pin raqamlariga ulang.
