Membuat Alat Pelacak Posisi dan Kirim Sms dan Monitor Lokasi via sms ARDUINO

Membuat Alat Pelacak Posisi dan Kirim Sms dan Monitor Lokasi via sms ARDUINO

            Pada kesempatan kali ini saya akan menjelaskan mengenai bagaimana cara membuat sebuah alat yang dapat digunakan untuk melacak atau mendeteksi posisi suatu benda atau monitoring posisi suatu benda via sms, jadi ketika kita kirim sms ke alat berupa text ''Monitor'' maka akan dibalas dengan posisi alat yang berupa koordinat longitude dan latitude. untuk lebih jelasnya berikut adalah skema dan programnya. 

a. Arduino Uno

b. LCD 16x2 + I2C

c. Modul GPS Ublox Neo 6Mv2

d. Modul SMS SIM800L

e. Modul Buck Converter / Step down

f. Program Arduino Uno
