ABSTRAK
Perkembangan teknologi dalam dunia elektronika sekarang ini maju
dengan pesatnya, dimana teknologi tersebut dikembangkan dan terus
dikembangkan guna memunculkan teknologi yang lebih handal. Mikrokontroler
merupakan salah satu produk teknologi yang dapat diumpamakan sebagai bentuk
minimum dari sebuah mikrokomputer yang berukuran kecil, akan tetapi dapat
melakukan berbagai macam perintah dengan kecepatan tinggi.
Pada tugas akhir ini, dirancang suatu alat bantu parkir mobil. Pada
dasarnya sistem ini terdiri dari satu bagian utama. Sistem pada pengukuran jarak
yang dirancang terdiri dari 1 sensor adalah sensor PING yang mempunyai
kemampuan sebagai alat pengukur jarak dengan memancarkan gelombang
ulrasonik. Sensor PING akan memancarkan gelombang ultrasonik pada objek
yang telah ditentukan, data jarak yang telah didapat oleh sensor PING akan di
proses oleh mikrokontroler Atmega16, kemudian hasil data proses yang di olah
oleh mikrokontroler akan di tampilkan di LCD dan IC ISD1420 berfungsi sebagai
tempat penyimpan data suara yang direkam. Data yang direkam IC ISD1420 akan
mengeluarkan hasil suara jarak yang telah ditentukan, kemudian motor DC akan
bergerak menarik pedal rem pada saat jarak yang telah ditentukan. Hasil
pengukuran jarak tersebut ditampilkan pada LCD secara real time.
Berdasarkan percobaan yang dilakukan, perangkat sistem yang dirancang
berhasil direalisasikan dengan persentase keberhasilan 90% selama sistem masih
berada di dalam batas jangkauan.

ABSTRACT
Technological developments in the world of today's advanced electronics
with the rapid, where the technology was developed and continues to be
developed in order to bring a more reliable technology. Microcontroller is a
technology product that can be likened to a minimum form of a small
microcomputer, but can perform a variety of commands with high speed.
In this final project, a tool designed car park. Basically the system consists
of a main section. Distance measurement system designed to consist of 1 PING
sensor is a sensor that has the ability as a distance measuring device with
ultrasonic emit. PING sensor will emit ultrasonic waves at a predetermined object,
the distance the data has been obtained by PING sensor will be processed by the
microcontroller ATmega16, then process the data results in if the microcontroller
will be displayed on the LCD and IC ISD1420 serves as a voice data storage were
recorded. IC ISD1420 recorded data will release the results sound a predetermined
distance, then draw DC motor will move the brake pedal at a predetermined
distance. Distance measurement results are displayed on the LCD in real time.
Based on experiments conducted, the system is designed successfully
realized with a 90% success rate for the system is still within the limits of the
range.
