Hi In this instructable we are going to see how a raspberry pi can help the blind people using the user-defined voice instruction.
Here, With the help of the Ultrasonic sensor input to measure the distance we can voice guide the blind people to follow the path. Also, I am planning for the cheap module which could solve this problem guiding the way to the Blind people.
This is the Idea to implement them in the raspberry pi, which is being the very tiny full-featured computer in our palms. I will also soon make a software in the ubuntu os, So that person without the technical background can make use of it help Blind people.”
