A Battery is also required to power the Arduino. This is project will help blind people alot to avoid obstacles in their path. ... Arduino Uno - 300rs-500rs Ultrasonic Distance Sensor Module - HC-SR04 ...

VL6180X Time-of-Flight (ToF) Range Finder Sensor. VL6180 differs from other distance sensors as it uses a precise clock to measure the time taken by the light to reflect back from any surface. This ...

This project uses an ultrasonic sensor to measure distances in centimeters and controls a set of LEDs based on those distances. The project is designed for Arduino boards, and you can use it to build ...

Tongueduino: How Arduino and tongues can help the blind see Usually, hearing and touch are used in place of sight, but an MIT researcher named Gershon Dublon is using the tongue as a way to convey ...

Although the navigation for blind using ultrasonic is a complex process but here we will present only the hurdle detection procedure. The project make the use of UNO Arduino processor, ultrasonic ...

For all human beings’ vision is primary requirement to survive in fast-changing environment. Scientific glasses are there to improve the eye sight of visually impaired people. But for blind people ...

To measure wind speed and direction, most people turn the traditional cup anemometer and wind vane. Another less-known method is to use an array of ultrasonic transducers, which doesn’t need … ...

For the blind, being able to navigate the world around them using electromagnetic sensors and a small tongue-pad would be a godsend. This is in a very early stage of development, but it is ...
