Jam Digital Arduino RTC 7 Segment + Temperature

Halo semua !!

Ini adalah proyek saya, jam digital dengan RTC (Real Time Clock) dengan menggunakan Display LED dari 4 digit 7 segmen, selain menampilkan jam terdapat fitur suhu dan kelembaban.

Untuk mengendalikan tampilan, saya menggunakan chip Arduino Uno dan 2 74HC595 (register geser 8 bit dengan kait output).

Ada dua modul: satu untuk sensor suhu (ºC - Celcius / º F - Fahrenheit derajat) dan kelembaban (% - dalam persentase) dan modul lain untuk RTC.

Rakitan sangat sederhana tapi Anda perlu berhati-hati dengan kabelnya.

Bersabarlah, ikuti skema dan nikmati.
