4. Prinsip Kerja Rangkaian & Listing Code [Kembali]

Pada rangkaian tersebut, modul sensor PIR dan sensor sentuh (touch) masing-masing dihubungkan sebagai input ke pin GPIO mikrokontroler STM32F103C8, sedangkan tiga LED (merah, hijau, dan biru) serta buzzer dihubungkan sebagai output pada pin GPIO lainnya. Di dalam kode, mikrokontroler secara terus-menerus membaca status pin PIR dan pin touch: jika sensor PIR  mendeteksi gerakan (membaca nilai SET)  maka mikrokontroler akan mengaktifkan pin Merah , serta membuat buzzer berbunyi; kemudian, jika kondisi sensor sentuh mendeteksi sentuhan (membaca nilai SET), maka mikrokontroler akan mengaktifkan pin Hijau, serta membuat buzzer berbunyi;
