Our project answers to two SDGs problem we think are important : good health and well being as well as reducing inequalities.
Our glasses was created from cheap components. We've gotten a pair of black genderless glasses on which was fixed a motion detector HC-SR04. It is working thanks to an Arduino Pro Micro powered by a power bank linked to an USB cable. There always are two buzzers on each sides of the glasses to make a sound and alert the wearer.
To make everything work, we've created programs for the distance sensor and the buzzer. We've decided to have sound only if the distance if below 3m. Moreover, the closer the distance is, the higher the frequency of the buzzer gets. Since blind people are more aware of there other senses, they can easily understand the difference between each frequency and then, know at what distance is the obstacle.
