b. Prinsip Kerja

Percobaan ini bertujuan untuk mendemonstrasikan implementasi sistem penghitung digital menggunakan DIP switch sebagai input dan dual seven segment sebagai output, dengan komunikasi serial antar modul Arduino. dengan komponen DIP switch Dual seven segment Dua modul Arduino (Arduino master dan Arduino slave) untuk koneksinya DIP switch terhubung ke input digital Arduino master. Dual seven segment terhubung ke output digital Arduino slave. Komunikasi serial (SPI) terjalin antar modul Arduino melalui pin MOSI, MISO, SCLK, dan SS/CS. DIP switch berfungsi sebagai input digital untuk Arduino master.

Program pada Arduino master dirancang untuk mendeteksi status DIP switch dan menentukan kondisi yang aktif (3 atau 4 switch aktif). Ketika kondisi aktif terpenuhi, Arduino master mengirimkan perintah melalui komunikasi serial SPI ke Arduino slave. Arduino slave menerima perintah dari Arduino master dan mengontrol dual seven segment untuk menampilkan angka yang sesuai dengan kondisi aktif yang terdeteksi.
