Alat Pakan Ikan Otomatis Berbasis IOT Blynk 2.0 ESP8266

Alat Pakan Ikan Otomatis Berbasis IOT Blynk 2.0 ESP8266

        Pada kesempatan kali ini saya akan menjelaskan mengenai bagaimana cara membuat sebuah alat yang dapat memonitoring pakan ikan secara online. jadi alat ini bisa memonitor volume pakan ikan sudah habis atau masih ada. alat ini menggunakan monitor Blynk 2.0 dan sensor jarak HY-SRF05. untuk lebih jelasnya berikut adalah koding dan skemanya.
