    This project allows the application of social inclusion within the SONVA Society, through the development of a Braille keyboard for computers, thus solving the need for a device with these characteristics for SONVA which focuses on people with 100% visual impairment to promote their typing. The main motivation with which this project was developed is the marginalization of society towards individuals with visual impairment, among the problems encountered is that, in the technological field there are no devices that apply typhotechnology and have easy access for the people of our city, at the end of the studies conducted at the SONVA Society located in Cuenca - Ecuador, triggers the need for a Braille keyboard that allows writing on computers. Therefore, a strategic investigation was carried out for the development of an electronic device that is controlled with a free, programmable hardware board (Arduino Leonardo), which allows the sending of characters in ASCII code, once the combinations prior to processing are processed. Your shipment to the computer. As a final result, a Play Station 2 control was reused, the Braille keyboard configuration was set and it was configured with the 6 points in Braille alphabet, by pressing the Braille device keys the person with visual impairment can enter The letter you want, this process is validated in a microcontroller, which sends the generated character to the computer and listens to it by using a free voice software (Windows Narrator) that allows you to listen to the letter entered, the Braille hardware is configured as a universal keyboard when connecting to a computer and functioning correctly through a USB connection.
