It cost me just 10 to make one.
Smart blind stick project description.
You need to click on above button in order to buy this project s code and simulation.
Through this the blind person can aware about the obstacles in front of him.
The main objective of this project is to help blind people to walk with ease and to be warned whenever their walking path is obstructed with other objects people or other similar odds.
Blind stick is an innovative stick designed for visually disabled people for improved navigation.
One is the main circuit which will be mounted on the blind man s stick.
The main board s circuit diagram is shown below.
Besides that the smart blind stick can provide longitude and latitude of the blind people location.
As a warning signal a buzzer is connected in the circuit whose frequency of beep changes according to the distance of object.
I used ultrasonic sensor for detecting the obstacles.
This project is a smart stick which is capable of detecting any obstacle detect water and corners and even allow the user to find the stick if anyhow missed by the user by pressing a remote switch.
The push button is add up to make the blind people easier to click the emergency button to inform the recipient that he she already lost or in danger.
The smart blind stick automatically detects the obstacle in front of the person and give him a response to the person by vibrating the stick and also with a warning sound.
That s why i thought of sharing this simulation.
Pdf smart blind stick project using arduino and sensors dagi fabri academia edu academia edu is a platform for academics to share research papers.
The other is a small remote rf transmitter circuit which will be used to locate the main circuit.
This arduino smart blind stick project requires two separate circuits.
We here propose an advanced blind stick that allows visually challenged people to navigate with ease using advanced technology.
The blind stick is integrated with ultrasonic sensor along with light and water sensing.
