Tugas Pendahuluan M1
MODUL 2 PERCOBAAN 1 KONDISI 5
- Pahami terlebih dahulu kondisi yang akan digunakan
- Buka software Proteus 8.17
- Persiapkan alat dan bahan
- Buat rangkaian sesuai dengan kondisi dan modul
- Buka software STM32Cube IDE
- Setelah membuka software, pilih perangkat STM32F103C8T6
- Sesuaikan konfigurasi pin sesuai dengan rangkaian proteus
- Buat kode program untuk mengoperasikan rangkaian tersebut sesuai dengan kondisi
- Konfigurasi kan program dengan software Proteus
- Jalankan simulasi rangkaian.
- Proses selesai
2. Hardware dan Diagram Blok[Kembali]
- Hardware
1. STM32F103C8
2. Touch Sensor
3. PIR Sensor
4. LED
5. Buzzer
6. Resistor
- Diagram Blog
3. Rangkaian Simulasi dan Prinsip Kerja[Kembali]
- Sistem dalam keadaan OFF
- LED dan buzzer dalam keadaan mati
- Sensor belum mempengaruhi output
- PA0 digunakan sebagai interrupt eksternal
-
Setiap menerima logika HIGH (1):
-
Sistem akan berubah kondisi (toggle):
- OFF → ON
- ON → OFF
3. Kondisi Sistem ON
- Sistem mulai aktif
- STM32 mulai membaca input dari sensor lain (PIR)
Jika PIR (PA1) = HIGH (1)
- Menandakan ada gerakan
-
Maka:
- LED (PB0) menyala
- Buzzer (PB1) aktif
Jika PIR (PA1) = LOW (0)
- Tidak ada gerakan
-
Maka:
- LED mati
- Buzzer mati
-
Sistem akan berubah kondisi (toggle):
