Raspberry Pi Project: IOT Door Lock

IOT Door Lock adalah projek untuk membuka dan mengunci pintu menggunakan servo motor. Ia boleh dikawal melalui mobile application dengan sambungan wifi. Selain itu, ia juga memantau bacaan suhu dan kelembapan. Sekiranya pintu dipecahkan iaitu limit switch terbuka pada ketika servo mengunci, buzzer akan berbunyi. Bagi versi NodeMCU ESP8266, boleh rujuk NodeMCU Project: IOT Door Lock.

Skematiknya adalah seperti berikut.

PCB komponen layout nya adalah seperti berikut.
