Arduino Assistive Technology for the Visually Impaired

This contraption uses servos and buzzers that react to the read distance returned by 2 ultrasonic distance sensors. So if you’re blind and somehow you managed to read this and thought the pictures were cool the next thing that you have to do is put the really small parts together without being able to see them, easy right, after that you will no longer be breaking your nose and stubbing your toes on things so yeah totally worth it. On both shoulders you will have an ultrasonic distance sensor that returns the distance which a servo (on the same shoulder) that presses a specific amount (depending on the distance), and when the item (thing that the distance sensor is seeing) comes too close a buzzer, on the same shoulder, beeps quietly just to emphasise that there is an object right next to your shoulder.”
