Dengan menggunakan arduino kitapun juga bisa membuat ringtone seperti pada handphone-handphone jaman dahul (jadul). Caranya adalah kita sisipkan kode ringtone atau istilah resminya RTTTL Code ke dalam program yang sudah kita buat kemudian kita upload programnya ke dalam arduino.
Cara merangkainya seperti gambar di bawah ini:
Dan berikut ini adalah program yang harus dimasukkan ke dalam arduino:

Kodenya lumayan panjang memang, itu karena kode di atas terdiri dari beberapa lagu. Kita bisa memilih lagunya dengan cara menghilangkan tanda // di depan //char *song.
Kitapun bisa menambahkan lagu-lagu yang lain asalkan kita tahu kode RTTTL dari lagu tersebut. Untuk mencarinya kita bisa menggunakan bantuan mesin pencari GOOGLE dengan keyword RTTTL CODE.

Kodenya lumayan panjang memang, itu karena kode di atas terdiri dari beberapa lagu. Kita bisa memilih lagunya dengan cara menghilangkan tanda // di depan //char *song.
Kitapun bisa menambahkan lagu-lagu yang lain asalkan kita tahu kode RTTTL dari lagu tersebut. Untuk mencarinya kita bisa menggunakan bantuan mesin pencari GOOGLE dengan keyword RTTTL CODE.
