Setelah program di download ke mikrokontroler, Relay Akan Mengalami Kondisi Terbuka Dan Tertutu Selama 1 Detik, begitu juga dengan lampu.
4.4. Pengujian koneksi modul GSM Wavecom dengan Mikrokontroller ATMEGA32 via serial max232
Pada pengujian komunikasi serial ini, kita lakukan dengan cara mengkomunikasikan mikrokontroller dengan komputer menggunakan kabel serial
yang terhubung ke mikro melewati IC MAX232. pengujian dapat dilakukan dan dapat dilihat pada hyper Terminal yang sudah ada pada Windows.
Pengujian pada hyper terminal ini akan muncul beberapa pilihan yaitu pilih
Universitas Sumatera Utara
Com1 dan pada bit per second baud pilih 9600. Dalam pengujian komunikasi serial ini kita harus memperhatikan perhitungan clock generator
pada mikro, karena cristal yang harus dipergunakan harus menggunakan perhitungan. Hal ini diperlukan agar data yang masuk bener-bener bisa
dibaca oleh komputer. Dalam pengujian ini menggunakan crystal 11.059200 MHz.
Mikrokontroller dikomunikasikan secara serial dengan wavecom fastrack 1306 b selanjutnya akan mengirimkan SMS di HP user pemilik rumah, untuk
mengetahui kondisi pintu atau jendela.dalam Pengkabelanya kondisi RX wavecom dihubungkan dengan TX mikrokontroller begitu pula sebaliknya.
Berikut adalah program untuk mengirimkan sms ke no hp tujuan

putchar13; printfAT+CMGS=;
putchar; printf+6285261065610;
putchar; putchar13
printftes modul wavecom; putchar26;
} }
Jika program dijalankan, maka mikro akan memerintahkan modul gsm untuk mengirim pesan yang berisi karakter “tes modul wavecom”.
