Electronic Accurate Distance Meter I s prototype that implements a distance measurement system using the ultrasonic waves. This prototype system is controlled by Arduino Mega. Aim of this project it helps to facilitate more accurate measure distance without any problem. With this project without the help of others to measure the distance. The project implements the distance measurement and obstacle detection technique where by the distance measurement and obstacle will reflect back the ultrasonic wave induced by the ultrasonic transceiver which then indicates the surface object and distance of the obstacle. When ultrasonic distance measuring something issued the LCD display shows the distance object. An Arduino Mega microcontroller is used to control the distance and receive data from ultrasonic sensor and removing the LCD display. As the result, this project shows in a little LCD display the distance to the nearest object it can find, usually the floor, the ceiling and two walls. So it can be so helpful to hang the picture and a shell. In conclusion, it easier for the public to measure distance accurately.
