RANCANG BANGUN SISTEM OTOMATISASI MENGGUNAKAN SENSOR JARAK ULTRASONIK UNTUK APLIKASI PENGEREMAN PADA MOBIL BERBASIS MIKROKONTROLER ATMega8535

Abstract

The Planning and realization of the automation system prototype of the car braking use the ultrasonic censor base on ATMega8535 microcontroller has been done. This equipment is used as security system to avoid accident of the car.. System consist of hardware and software. Hardware consists of ultrasonic censor, ATMega8535 microcontroller, LCD ( Liquid Crystal Display), and DC motor. Ultrasonic transmitter sends a signal with frequency of 40KHz. In the moment of this delivery will activate the internal timer of microcontroller, and will desist when bound signal accepted by receiver. This data is then processed by microcontroller become distance and presented by LCD. Motor DC will desist when appearance at LCD shows scale of 30cm. The realization of the system has been done and can measure distance with mistake tolerance of 2% and can give command to stop DC motor.
