Membuat Alat Pengisian Air Otomatis (Pertamini) Berbasis Arduino

Membuat Alat Pengisian Air Otomatis (Pertamini) Berbasis Arduino

       Pada kesempatan kali ini saya akan mejelaskan mengenai bagaimana cara membuat sebuah alat yang dapat digunakan untuk mengisi air secara otomatis seperti pertamini, jadi sistem kerjanya yaitu user menekan keypad berapa ml yang dia butuhkan lalu tekan start untuk memulai pengisian air, alat ini juga dilengkapi sensor IR proximity sehingga jika belum ada gelas untuk menampung airnya maka ketika ditekan start airnya tidak akan mengalir. jadi yang dibutuhkan adalah adanya benda / gelas untuk menampung air dan tombol start ditekan. jika air sudah sesuai dengan yang diinginkan maka relay akan off kan solenoid agar air tidak mengalir. untuk lebih jelasnya berikut adalah skema dan kodingnya.

c. Cara Penggunaan Alat

         Jadi alat ini yang pertama mengisi nilai kuantitas air yang diinginkan menggunakan keypad lalu tombol A untuk memilih 250 ml. tombol B untuk memilih 500 ml. C untuk memilih 750 ml dan tombol D untuk 1000 ml. jika ingin custom bisa menggunakan keypad pakai angka 0 sampai 9. jika ingin clear tekan # lalu jika ingin memulai pertamakali harus dekatkan gelas sampai sensor mendeteksi kemudian tekan tombol start untuk memulai pengisian, jika pengisian sudah sesuai takaran maka pengisian akan berhenti secara otomatis.
