Smart Blind Stick Project

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.
