LAMPIRAN-LAMPIRAN


Lampiran 1 Diagram alir program selengkapnya Mulai Inisialisasi Input Alarm Warning Inisialisasi Input Alarm Critical

Catat status alarm di microSD

Koneksi WiFi ke Android?

Tidak

Ya Kirim Alarm Status via WiFi Tampilkan Status Alarm di Aplikasi Android Switch Alarm diaktifkan

Ya

Alarm Warning aktif? Tidak Alarm Critical aktif? Tidak Matikan Arduino Putus Koneksi WiFi Android

Selesai


Ya

Koneksikan WiFi Android ke Arduino
