Belt for Blinds

An android application which takes as input the distance data from an Ultrasonic sensor connected to an Arduino board.
The data is transmitted over Bluetooth and the application processes the data to output as speech a suitable message so that the visually impaired can find their way around.
Here is a video demonstration: https://www.youtube.com/watch?v=nyt1adewqL4

Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes. See deployment for notes on how to deploy the project on a live system.
Clone this project. git clone https://github.com/Pankaj-Baranwal/Belt-For-Blinds
Open in Android Studio
The folder bluetooth_working contains the Arduino code for Ultrasonic sensor control which needs to be burnt on an Arduino board.

Prerequisites

What things you need to install the software

Arduino IDE
Android Studio

Deployment

Connect Ultrasonic sensor (like HC-SR04 model) to Arduino using this guide: http://playground.arduino.cc/Main/UltrasonicSensor
Connect Bluetooth module to Arduino with primary RX and TX so that Serial.print command works.
Run the installed app on an Android phone and connect to the Bluetooth module which has default name as HC-05.
