Abstract
Abstract: In this paper we are going to discuss the implementation and working of smart blind stick for obstacle detection and navigation. This project is implemented to provide a smart electronic guide for blind people. Different kinds of blindness and visual impairment makes people difficult to move from one place to another place. The main of our project is to provide some type of guidance to blind people while moving by helping them in detecting obstacles in their way via ultrasonic sensors, navigating them using GPS module and sending emergency message for rescuing them to caretakers using GSM technology. The system we proposed is an economical, easy-to-use solution for the blind to increase their mobility. Index Terms: Arduino UNO, Node MCU, ultrasonic sensors, APR9600 voice record playback module, GPS, GSM
