Raspberry Pi dan Alat Parkir UI Gladhi Guarddin, M.Kom adin@ui.ac.id

Tujuan Implementasi Raspberry Pi sebagai pengendali proses pengambilan data kendaraan pada gerbatama UI Setiap gambar yang dicapture akan diolah oleh aplikasi terpisah

Raspberry in a Box

Rangkaian in a Pipe {bomb} VCC 3.3V GPIO pin X GND

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 Execute Shell (background) & Python Controller read from GPIO capture jpg from IP Camera Execute Shell (background) & capture jpg from IP Camera Execute Shell (background) & capture jpg from IP Camera Execute Shell (background) & capture jpg from IP Camera
