Abstract

This paper reports on a study that helps visually impaired people walk more confidently. The study hypothesizes that a smart ultrasonic cane that alerts the visually impaired to obstacles ahead could help them walk with less accident. The aim of the post is to deal with the development work on a smart device that could communicate with users through a sound notification, which is called the Smart Ultrasonic Stick.The smart stick is supposed to use. Arduino UNO, Ultrasonic Sensor, LED and Buzzer module. Arduino is a microcontroller which can do all the calculations very easily and quickly with great accuracy. Ultrasonic sensor is used to detect the object in the front of the person by measuring the distance between the object and the stick. The Buzzer Module, is used here is to alert the person by making sound, this in return helps the user to reach his /her destination safely. A series of tests have been carried out on the smart stick and the results are discussed.
