Halo Rek! Kali Ruang Teknik akan share konversi rangkaian PLC untuk diimplementasikan ke dalam Arduino, seperti diketahui penggunaan PLC sangat membantu mengurangi cost biaya Relay/Kontaktor dalam sistem otomasi, sehingga sangat bermanfaat jika kita ingin membuat rangkaian listrik yang membutuhkan banyak Relay/Kontaktor.
Untuk video demo rangkaian bisa dicek disini
Ok, tanpa panjang kali lebar :) silahkan dicek rangkaian On dan Off + LED kedip dengan satu saklar.
Setelah dikonversi ke dalam bahasa pemrograman hasil seperti dibawah ini:
Berikut kodingannya
