Pakan Lele Canggih dengan NodeMCU dan Android menggunakan MQTT

Solusi memberi pakan lele bila anda sedang berpergian jauh, sayangi lele mu dengan tidak lupa memberinya makan… hihihi…

Sebaiknya sebelum membuat project ini, belajar dulu Apa Itu MQTT. Silahkan bisa gunakan link ini tytomulyono.com/apa-itu-mqtt

Langsung aja ga usah pake lama bray, tonton videonya dan sedot source code nya….


 

Tutorial ini untuk anda yang sudah faham dengan Arduino control dan MQTT sebagai koneksi IoT.

Download Arduino IDE bagi yang belum memiliki di situs resminya arduino.cc

Buka Arduino IDE File – Preferences – Aditional Boards Manager URL isi dengan :  http://arduino.esp8266.com/stable/package_esp8266com_index.json

Berikut Source Code nya, sedot gan….

Download Source Code disini.
