.: Stirer Kendali Jarak Jauh Online Blynk 2.0

Pada kesempatan kali ini saya akan menjelaskan mengenai bagaimana cara membuat sebuah alat yaitu Stirer Kendali Jarak Jauh Online Blynk yang mana fungsinya yaitu untuk mencampurkan cairan dan juga mengaduk secara otomatis dengan timer. alat ini diinput menggunakan aplikasi secara online jarak jauh sehingga memuahkan penggunaan. untuk lebih jelasnya berikut adalah koding dan skemanya.
