Rancang Bangun Alat Ukur Jarak Mengunakan Sensor Ultrasonik Berbasis Arduino Uno dengan Tampilan LCD

Abstract

The manual distance measuring instrument, in fact, having a problem with its data because of parallax error repeatedly. To decrease the error, the ultrasonic distance range (ultrasonic ruler) was designed. Using the HC-SR04, this instrument will help peoples measuring accurately. The data displayed on LCD module (liquid crystal display) sized 16 x 2. This instrument controlled by Arduino Uno R3 Kit based on ATMEGA 328 P, and implemented on the plastic plat as it place and cover
