Raspberry Pi danAlat Parkir UIGladhi Guarddin, [email protected]
Tujuan Implementasi● Raspberry Pi sebagai pengendali proses pengambilan data kendaraan
pada gerbatama UI● Setiap gambar yang dicapture akan diolah oleh aplikasi terpisah
Wiring Sensor
Raspberry in a Box
Rangkaian in a Pipe {bomb}
VCC 3.3V
GND
GPIO pin X
Rangkaian in a Pipe {bomb}
VCC 3.3V GPIO pin 8
GPIO pin 10
GPIO pin 12
GPIO pin 16
GND
Konsep Rangkaian GPIO● Normally True● Pull UP, nanti down kalau di short circuit dengan Ground● Mengapa perlu di Pull UP ? karena status GPIO nya adalah “Floating”
Konsep Aplikasi
Python Controllerread from GPIO
