A helper for blind people to walk on the roads
It has a sensor at the top of the cane. While a blind person is walking is walking on the road and if anything is in front of him it will detect and make a sound through speakers, also the cane vibrates.
In this way the person will come to know something there in front of him so in that way he can take precautions while walking.
While crossing a road if the car is moving the sensor detects and make the sound as well as it vibrates. so he can understand that the car is moving so we can avoid many accidents.
