Description A very Unique project which can help the people who can’t see. this can be a helping hand for those people. the smart blind stick project have an ultrasonic sensor which detect the obstacle in front of the Blind stick and start making sounds. The Smart Blind Stick scans the path in front of it with the help of an HC-SR04 Ultrasonic sensor. Whenever the sensor detects any object in its path the buzzer starts beeping and also at the same time the LED turns on. The blind person can hear the beeping of the buzzer and manage to change the way. In this way, the person can easily find his way without getting injured. This smart stick works in the same way as the Ultrasonic range finder did. You can also see the real-time values of the distance in cm on the Arduino serial monitor. Once the circuit is ready for this Arduino mini-project tie the whole set-up to a stick using zip ties.
