Membuat Water Mixer / Alat Pencampur Minuman / Cairan Menggunakan Arduino WIFI Ethernet Shield

Membuat Water Mixer / Alat Pencampur Minuman / Cairan Menggunakan Arduino WIFI Ethernet Shield


        Pada kesempatan kali ini saya akan membahas mengenai bagaimana cara membuat sebuah alat yang digunakan untuk mencampur minuman atau cairan, misalnya terdapat susu, teh, gula dan kopi, kemudian si pembeli ingin memesan kopi susu sehingga yang akan keluar dari alat adalah gula, kopi dan susu, begitu pula dengan menu yang lain seperti teh susu atau kopi / teh manis. yang menarik dari alat ini adalah si pembeli bisa memesan dengan dua cara yaitu bisa dengan manual atau tombol, selain itu pembeli juga bisa memesan melalui handphone mereka atau komputer yang terhubung ke sebuah router yang sama dengan alat ini, komunikasinya menggunakan wifi. untuk lebih jelasnya berikut adalah skema dan programnya.




a. Arduino + Ethernet Shield





b. Solenoid Valve 1/2 dim





c. UBEC 3A maks 5A





d. Router WIFI





e. LCD 20x4





f. Program Arduino IDE
