Electronic walking stick for blind circuit.

The main board s circuit diagram is shown below. Ultrasonic blind walking stick duration. Short paper an intelligent walking stick for the visually impaired people fig. The electronic walking stick will help the blind person by providing more convenient means of life.

This invention relates to an electronic talking stick for the blind and more particularly to a stick which talks to instruct a blind man to walk and go upstairs and downstairs and to warn a blind man of dangerous depression in road and which calls for help when a blind man who uses the stick falls. In the code a library is used by the name ultrasonic h this library is not added in arduino by default. 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. Electronic cane for blind and visually impaired.

Here one micro. Ultrasonic blind walking stick program code. These blind people are totally dependent on others as they can t walk alone. 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.

The generally available blind walking sticks are capable of finding obstacle that touch the stick physically. 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. The system uses a microcontroller based circuit to handle the entire system. 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. It is generally comprised of a supporting rod a control box a handle a free steering caster. The ultracane an award winning primary mobility aid. 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.

The other is a small remote rf transmitter circuit which will be used to locate the main circuit. Blind walking stick using arduino ultrasonic sensor hc sr04. Code file is given in the link just download this file and upload to arduino. The main aim of this paper is to contribute our knowledge and services to the people of blind.
