Pastikan proses Upload Berhasil dan tertera "Done Uploading".
Proses Upload akan memakan waktu lebih lama dibanding upload ke Arduino.

6.Setelah proses Upload selesai, buka Serial Monitor pada Arduino IDE pada boudrate 115200 - Newline.


akan nampak seperti gambar di atas (jika anda pakai coding diatas maka akan menggunakan bahasa inggris).Perhatikan pada IP Address yang tampil pada serial monitor.Itu adalah address ESP yang telah tergabung pada jaringan Wifi anda.

7.Buka Browser (Mozilla,Chrome,IE,UC,Safari,Opera) pada PC/Laptop atau Smartphone anda yang sudah tergabung dalam jaringan Wifi yang sama.Ketikan Address ESP yg ada pada Serial Monitor pada kolom alamat pada browser anda.
pada contoh kali ini alamat ESP saya adalah : 192.168.0.110

8.Anda dapat mengontrol LED1 - LED4 melalui tombol tombol yang tampil pada browser




Kontrol 8 Channel Relay Module melalui wifi menggunakan ESP8266 Nodemcu

Pada Tutorial kali ini kita membutuhkan :
-ESP8266 NodeMCU (4M lua wifi) baik yang pakai Uploader CH340 atau CP2102
-Kabel data Micro USB Untuk programming module ESP Nodemcu
-Relay Module 8 Channel (Low Active)
-Kabel Jumper Dupont Female to Female
-Software Arduino IDE 1.6.xx



Berikut Coding untuk Control Relay secara sederhana menggunakan ESP8266 Nodemcu
