The main idea of this paper is to design a theoretical model and a system concept to provide visually impaired people walk with ease and be warned whenever their walking path is obstructed with other objects, people or similar odds. The closer the distance of obstruction more will be the buzzer beep frequency which is inversely proportional to the distance. The main component used is ultrasonic sensor transmitting a high frequency sound pulse and then calculate the time to receive the signal of the sound and to reflect back. Arduino UNO is selected as the major platform.

Keywords : Visually-impaired, ultrasonic sensors, Arduino, buzzer etc.
