Membuat Alat Kendali Peralatan Rumah Tangga / RELAY Menggunakan WIFI dan INPUT Jadwal /Jam ON - OFF WEBSERVER ARDUINO RTC
Pada kesempatan kali ini saya akan menjelaskan mengenai bagaimana cara membuat sebuah alat yang menggunakan wifi sebagai media alat kendali ON/OFF device dengan input jadwalnya menggunakan browser, jadi sistemnya yaitu webserver yang mana user bisa memasukkan jam dan tanggal kapan alat hidup dan kapan alat mati secara otomatis dengan menggunakan browser, koneksi yang digunakan yaitu wifi sehingga memudahkan user untuk instalasinya, alat ini menggunakan Arduino sebagai kontrollernya dan ethernet shield sebagai jembatan menuju ke WIFI. alat ini juga dilengkapi dengan RTC DS1302 dan 4 buah relay sebagai kendali device, jadi jika jam sekarang sudah sama dengan jam yang diinputkan maka device akan on/off sesuai jadwal yang dimasukkan. untuk lebih jelasnya berikut adalah skema dan programnya.
