Perancangan Alat Ukur Jarak dengan Menggunakan Mikrokontroller Atmega 8535 dengan Tampilan Lcd

Abstract

The development of electronic technology, especially in the field of microcontrollers occur very rapidly. Has a lot of application and utilization of microcontrollers that are useful in everyday life as well as in the research laboratory. In this project task used ATmega 8535 microcontrollers from Atmel products as a measure of distance by using Ultrasonic Distance sensor to determine the distance of an object with high accuracy. Ultrasonic sensor has a frequency of 40 KHz. The sensor consists of a transmitter and receiver of ultrasonic waves. Transmitter will emit a series of ultrasonic waves in a time of 200 microseconds. This wave through the air at speeds of approximately 344 m / sec.If this wave of an object, then this wave will be reflected back to the receiver of ultrasonic sensors. The method used is to utilize (Timer / Counter) that already exist in the microcontroller. Microcontroller ATmega 8535 has speeds up to 8MHz frequency generator, the ability of 8-bit counter, as well as using the C language as a programming language. Code Vision AVR is one of the software that uses Code Vision AVR C language was designed by considering the encoding properties of the C language compiler generated so that a program can be as small as possible and as quickly as possible. The result of the design of this tool will be obtained from the object distance measurement ultrasonic wave sensor with a microcontroller Atmega 8535.
