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.

Currently, having a sonar of echolocation in an electronic lab is complicated due to the high cost of its implementation, which is why it is proposed that the implementation of a basic sonar, using agile technologies such as the Arduino, will be used to implement this paper. Also it has a servomotor and an ultrasonic sensor, which is responsible for detecting the distance where the objects are located. The Arduino will be in charge of controlling the servomotor movements which have to be between 15 and 165 degrees. In addition, it will send the information through the serial port to a computer, in which the data will be processed and displayed using the Processing software.
