bagaimana agar Arduino bisa menerima data dari web / remote jarak jauh menggunakan surel Http atau Https.
Sebagai berikut adalah source code yang digunakan. Adapun contoh penggunaanya bisa dilihat pada video sebagai berikut :

met siang master andy.......
BalasHapuskayak komputer kecil ya......
kira kira modul di atas bisa gak ya untuk membuat aplikasi seperti ini :
suatu misal saya ingin menampilkan nilai 2counter di vb (GUI yang lain juga gak apa apa).
masing masing counter menggunakan mikrokontroler.
comunikasi antara mikrokontroler dengan GUI menggunakan internet (LAN).
selain dapat di accses melalui PC nilai counter tersebut juga dapat di accses via android.
nilai counter tersebut juga dapat di simpan diexel.
untuk membuat aplikasi seperti tersebut di atas kira kira total biayanya berapa ya master????
saya tunggu kabar baik dari master andy.....
salam.
joko.
