Smart Stick for Blind People

Abstract

Ever heard of Hugh Herr? Hugh Herr's legs were amputated below his knees in 1982 after a climbing accident. From his knees down to the floor, he's completely artificial. . Hugh Herr once said “We're beginning the age in which machines attached to our bodies will make us stronger and more efficient.”. These were not just words but he lived his life to them, today he uses Prosthetic legs and claims to live to normal life. So yes, technology can indeed neutralize human disability; with this in mind let us use some simple development boards and sensors to build an ultrasonic blind walking stick using Arduino that could perform more than just a stick for visually impaired persons. This Smart stick will have an Ultrasonic sensor to sense distance from any obstacle. All outputs will be obtained through Buzzer module and vibration motor to alert Blind person.
