Smart Stick for Blind People

Abstract

As we know that sense of vision to human being is an important thing in our life, but there is some people who have lack of mobility because of blindness The objective of this project is used to help the blind people and they are able to easily interact with the physical world by using this smart blind stick. About 285 million people are visually impaired worldwide: 39 million are blind and 246 million have low vision. If you notice them , you can very well know about it they can’t walk without the help of other. One has to ask guidance to reach their destination. Using this blind stick , a person can walk more confidently. This stick with ultrasonic sensor detects the object in front of the person and give response to the user by alarm from the buzzer, which will give a high buzz as the object gets closer to the blind person. So, the person can walk without any fear. The LDR sensor are used in the stick to identify the day and night for the blind people. The microcontroller (Arduino Nano) to receive the sensor signals and process them to short pulses to the Arduino pins where buzzers are connected. This device will be best solution to overcome their difficulties and help
