Design and Implementation of a Telescope for Blind People based on an Atmega Controller

Abstract

In this research a design of glasses for blind people has been developed using an Atmega controller (Arduino nano) and a sensor (ultrasonic), people who have visual problems struggle all the time with the problem of mobility, that is, moving from one point to another without having accidents with the obstacles in their way. The aim of this research is to make an electronic device capable of detecting obstacles for blind people, in order to offer blind people the possibility of having a new resource to help them detect the obstacles and thus have better movement. For the project, an Arduino nanocontroller was used, an ultrasonic sensor as an obstacle detector, a buzzer to generate a warning sound and a program developed based on the calculation of the distance to the obstacle. This research will focus on the following stages that correspond to evaluate the main difficulty of a blind person, the development of the device, development of the Arduino programming, tests of the functionality of the device, implementation and conclusions.
