raspberry pi dan alat parkir ui

Raspberry Pi danAlat Parkir UIGladhi Guarddin, M.Komadin@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

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
