KATA PENGANTAR

Dengan memanjatkan puji syukur kehadirat Allah SWT atas limpahan

rahmat, nikmat, hidayah, dan ridho-Nya, sehingga peneliti dapat menyelesaikan

Skripsi yang berjudul:

“PERANCANGAN DAN PEMBUATAN ALAT PENGONTROL NADA

(TONE CONTROL) OTOMATIS MENGGUNAKAN RASPBERRY PI”

Di dalam tulisan ini disajikan pokok-pokok bahasan yang meliputi

pengoperasian perangkat – perangkat yang digunakan seperti Raspberry Pi,

Arduino Mini, dan Motor Servo. Kemudian mempelajari juga bagaimana

membuat dan menghubungkan koneksi antar perangkat. Juga mengetahui

bagaimana cara menggerakan motor servo agar dapat berputar ke kanan dan ke

kiri dengan menggunakan program, untuk memutar Tone Control.

Peneliti menyadari sepenuhnya bahwa dalam penulisan tugas akhir ini

masih banyak kekurangan dan keterbatasan. Oleh karena itu peneliti

mengharapkan saran yang membangun agar tulisan ini bermanfaat bagi

perkembangan ilmu pengetahuan kedepannya.
