Membuat Alat Pengaman Berbasis Camera Linksprite dan Foto / Gambar disimpan di SD card Arduino


       Pada kesempatan siang hari ini saya akan menjelaskan mengnai bagaimana cara membuat sebuah alat yang dapat digunakan untuk pengaman ruangan / rumah menggunakan camera, jadi prinsip kerja alat ini yaitu akan meng-capture atau ambil gambar / foto saat ada orang masuk, lalu gambar atau foto yang dihasilkan disimpan ke SD Card, sensor yang digunakan untuk mendeteksi orang adalah sensor proximity yang mana jaraknya bisa diatur menggunakan potensio dibelakang sensor. camera yang digunakan pada percobaan ini adalah camera linksrite serial inteface, untuk lebih jelsnya berikut adalah skema dan programnya.



a. Arduino Uno + Skema






b. Camera Linksprite JPEG Color TTL Interface






c. SD Card Module





d. Sensor Proximity





e. Skema Pemasangan

// Note:
// 1. SD must be formated to FAT16
// 2. As the buffer of softserial has 64 bytes,
//    so the code read 32 bytes each time
// 3. Please add the libaray to the lib path
//
// * SD card attached to SPI bus as follows:
// * MOSI - pin 11
// * MISO - pin 12
// * CLK - pin 13
// * CS - pin 4
