Electronic Walking Stick For Blind Circuit

The generally available blind walking sticks are capable of finding obstacle that touch the stick physically.

Electronic walking stick for blind circuit.

One is the main circuit which will be mounted on the blind man s stick. Ultrasonic blind walking stick duration. The main aim of this paper is to contribute our knowledge and services to the people of blind. In the code a library is used by the name ultrasonic h this library is not added in arduino by default.

It is helpful to a blind person but we here propose an advanced blond stick system that allows blind person to sense objects before stick touches them. Circuit digest recommended for you. Almost 30 million people are blind according to the recent who report. Here one micro.

Ultrasonic blind walking stick program code. Developing safer alternatives since 2010 the ultracane is a primary electronic mobility aid for use by people who are blind or visually impaired and is the only electronic mobility aid that utilises state of the art narrow beam technology allowing the user to safely avoid obstacles and navigate around them both in the user s forward. Electronic cane for blind and visually impaired. The walking stick mentioned above is a stick that consists of a circuit board that contains a pic micro controller a led for indication input from micro pager motor inputs from sensors that are installed at proper the micro controller is code protected so its security bridge cannot be override except the vendor or owner.

It is generally comprised of a supporting rod a control box a handle a free steering caster. The main board s circuit diagram is shown below. The ultracane an award winning primary mobility aid. The electronic walking stick will help the blind person by providing more convenient means of life.

Simulation of the blind stick via proteus 8 0 fig. Short paper an intelligent walking stick for the visually impaired people fig. The system uses a microcontroller based circuit to handle the entire system. 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. In this project we will learn how to design blind walking stick using arduino ultrasonic sensor hc sr04. Simulation of the blind stick via proteus 8 0 3 2 hardware development for two push button connection in the proposed model two push buttons are used as shown in ig 5 one for senf d. Blind walking stick using arduino ultrasonic sensor hc sr04.
