Pet Feeder Otomatis Menggunakan Arduino dengan setting waktu via Android dan SMS Gateway

           Pada kesempatan kali ini saya akan menjelaskan mengenai bagaimana cara membuat alat yang bisa digunakan untuk memberikan makanan kepada hewan peliharaan seperti ikan atau kucing dll. secara otomatis dengan set waktu menggunakan handphone android dan sms, kemudian terdapat motor servo yang digunakan untuk buka-tutup pintu atau katub. alat ini juga dilengkapi dengan sensor jarak yang bisa mendeteksi kondisi pakan ketika masih full atau sudah mau habis. untuk lebih jelasnya berikut adalah skema dan programnya.   

a.Arduino Uno

b. Motor Servo

c.Bluetooth HC-05

d. Modul SMS SIM900A

e. LCD 16x2 I2C

f. RTC DS1302

g. Program Android

h. Program Arduino Pet Feeder
