Alat Pakan ikan Otomatis Monitor Ph turbidity suhu dan water level IOT Blynk 2.0

Alat Pakan ikan Otomatis Monitor Ph turbidity suhu dan water level 

 

        Pada kesempatan kali ini saya akan menjelaskan mengenai bagaimana cara membuat sebuah alat untuk pakan ikan otomatis dan mengukur PH Turbidity Suhu Amoniak Water Level IOT Blynk. jadi alat ini menggunakan arduino nano dan esp32. untuk lebih jelasnya berikut adalah kodingnya.
