Help making Hearing aid
I need a bit of help for a project I am undertaking to make.My is to make such a device which detects the user whether a car or any other vehicle is approaching or not.
The project is dedicated for the people who are deaf and cannot cross roads safely.
What I think a solution could be is to make such a sensor which detects the horn of a car which further activates a vibrating motor in the pocket of the user.The vibratng motor is not at all an issue but the sensor being the problem.
If anyone can please help either by giving your own solution or helping me in what I propose to do.
Please help as this is not anything personal but a social cause.
Hope to get an answer.
