METHODOLOGY

When the object is detected near to the shoe and if any person coming in front it alerts them with the help of vibratory circuit and also in advancement with help of speakers or headphones that is voice command.

To implement, the ultrasonic sensors, Arduino microcontroller and SD card are used. Based on signals, the decision is made in Arduino to manage and give timely signals. The input string is from the ultrasonic sensors which generate high-frequency sound waves and evaluate the echo which is received back by the sensor. Sensors calculate the time interval between sending the signal and receiving the echo to determine the distance to an object. The ultrasonic sensor can measure distances in centimeters and inches.

When the obstacle is located in far distance sensor will detect and intimate with the low-frequency buzzer sound.When the obstacle is located in a short distance less than the sensor will detect and intimate with high-frequency buzzer sound
