Perancangan Alat Bantu Tunanetra Menggunakan Sensor Utrasonik Berbasis Arduino yang Diaplikasi-kan pada Rompi

Abstract

Blind people generally use a cane as a guiding tool in daily activities. Advances and developments in technology make an equipment with an arduino-based ultrasonic sensor that helps people to move more freely. Ultrasonic sensors work by utilizing ultrasonic waves as transmitters and calculating distances with time difference. Ultrasonic sensor sensitivity from 2cm to 200cm. The data management used is an Arduino microcontroller and output in the form of sound from a buzzer, and has the feature of detecting the user's presence via GPS if the push button is pressed.
