Alat Pakan Ikan Otomatis dan Monitor PH Turbidity dan Suhu IOT Blynk
Pada kesempatan kali ini saya akan menjelaskan mengenai bagaimana cara membuat sebuah alat yang dapat memonito PH Turbidity (Kekeruhan Air) dan suhu serta ada fitur on off pelontar pakan secara otomatis sesuai waktu yang disetting. untuk lebih jelasnya berikut adalah kodingnya.
