Smart Arduino Walking Stick for Visually Impaired

The smart walking stick is a very interesting project and ideal for beginners. The main aim of this stick is to alert the visually impaired about an obstacle in his way. Whenever the sensor detects any object in a range of 60 cm it triggers the buzzer.

This project can also be used as a distance finder. (by using serial monitor)
