Smart Blind Cane With Alarm Kit And Location Sharing System

To provide a better and safe independent experience to blind people in their daily lives, suffering with ophthalmological diseases, an attempt has been made to develop an Arduino based multi-sensor driven blind helper stick. This stick can guide the visually challenged people to move around freely using the ultrasonic sensor and proximity sensor integrated with it by detecting necessary obstacles or dead-end present around and alerting them with the alarm unit consisting of vibrator and buzzer attached in the stick. Also, a GSM module is present that sends a message with current location to a preset number when triggered with a button by the user.
