3. Rangkaian Simulasi[Kembali]
- Rangkaian sebelum di running
- Rangkaian setelah di running
- Prinsip Kerja
Rangkaian menggunakan sensor touch dan sensor infrared (IR) sebagai input yang diproses oleh mikrokontroler STM32F103C8, dengan output berupa LED dan buzzer. Ketika sistem dinyalakan, mikrokontroler terlebih dahulu melakukan inisialisasi, kemudian secara terus-menerus membaca kondisi dari kedua sensor.
Sensor touch akan memberikan logika HIGH saat disentuh, sedangkan sensor IR akan mendeteksi keberadaan objek di depannya. Selanjutnya, mikrokontroler akan memproses kedua input tersebut sesuai dengan kondisi yang telah ditentukan, yaitu ketika sensor touch dalam keadaan disentuh dan sensor IR tidak mendeteksi objek, maka LED akan menyala sebagai indikator.
Namun, jika salah satu kondisi tidak terpenuhi, seperti sensor tidak disentuh atau sensor IR mendeteksi adanya objek, maka LED dan buzzer akan tetap dalam keadaan mati. Proses ini berlangsung secara berulang (loop) sehingga rangkaian dapat merespons perubahan kondisi secara langsung selama sistem bekerja.
