Introduction: Arduino Voiced White Cane (Part One)
Years ago, I was with a student who had a family member who was blind, I realized that we could arrive at a small solution capable of making audible how many steps there was some obstacle, obviously an arduino with previously recorded numbers could do the trick, to continuation some guidelines to which we got you solution
Step 1: Materials
-Arduino SD Reader
Step 2: The Software and Library
Step 3: Mounting Test
-All works at 5 volt
-No need (by now) extra power supply
-via the 9 pin you will get the audio
How to use the hardware:
The user must use the eaarphones and point he way he or she want to walk
so the circuit makes a routine that tells the user how many steps can take
i am assuming aregular step takes 60 cm or 2 feets
soo ill give the calibrable version.
Step 4: Audio Files
These are the audio files for every number, if you combine them you can make any number.
You can convert any file to wav, in this page.
Step 5: Program
Make sure you add the arduino library
Download the program, make shure you insert the sd card
Step 6: Video Test
We have a be nice policy.
Please be positive and constructive.
