Ultrasonic Sensory Device for the Visually Impaired

This project was done as a final exam for a college class. Both my lab partner, Chris and myself spent several weeks on this project and we’re fairly happy with the results. The idea behind this project is to assist the visually impaired with getting around without the need for a big long cane that just gets in the way. This device is compact and still allows the user to have use of their hands and without having to fold up and stow away a cane. This instructable will teach you how to create a device that uses an ultrasonic sensor to detect the distance of objects, and based on that distance, give an output of your desired intensity of vibration to help the user “feel” their surroundings using vibrations. This project is fairly complicated and requires some background in circuitry, soldering, and coding.”
