It is an Arduino based device which can be fixed to blind person’s stick to make them alert when anything is close to them. It gives out buzzer sound when the danger is very near to them. Ultrasonic sensor was interfaced with arduino, giving the exact distance from any object. Ultrasonic sensor sends out ultrasonic waves which get reflected back from the object infornt. This travel time is calculated and distance is measured.
