Kendali Pagar MANUAL / OTOMATIS via Sensor PIR dan IOT BLYNK 2.0

Kendali Pagar MANUAL / OTOMATIS via Sensor PIR dan IOT BLYNK 2.0

         Pada kesempatan kali ini saya akan menjelaskan mengenai bagaimana cara membuat sebuah alat yang dapat mengendalikan sebuah pintu pagar dengan 2 mode yaitu manual dan otomatis. untuk cara manual yaitu dengan menggunakan fitur IOT blynk yang terdapat 2 buah tombol untuk kendalinya sedangkan untuk fitur otomatis yaitu buka tutup pagar dengan menggunakan sensor PIR. untuk lebih jelasnya berikut adalah koding dan skemanya.
