Abstract: There are many visually impaired person in our society. If you notice them you can very well know about it they cant walk without the help of other. One has to ask guidance to reach their destination. They have to face more struggles in their daily life. Today technology is growing to a greater extent, however there is no cost effective device for visually impaired people. For a visually impaired person it becomes impossible to do his/her day to day activities, therefore Smart Blind stick can help people in moving and allowing them to perform their work easily they find difficulties detecting obstacles on the way of user, during walking in the street, which makes it very dangerous. The stick is a best way to identify the surrounding in this stick we are using in a smart stick with infrared sensor to detect stair cases and pair of ultrasonic sensor to detect any other obstacles in front of the user, within a range of four meters. And water sensor is also used which detects the water on the way of the user. All the detected obstacles are informed to the user through voice module as voice instructions. And GPS is also used which tells the user about his current location.
Keywords: Arduino, stick, voice module, ultrasonic sensor, IR sensor, water sensor, GPS, LDR sensor
