Artificial Digital Eyes For Blind

I have made this project, I have made this project for the help of people who cannot see with their eyes. This project does not cost much, all people can easily make it. It needs a micro controller and two echo sensors to make it.


The model number of this echo sensors is HC-SR04. Its total is 4 pins. The first voltage is 5 volts. Second is trigger, Number three is an echo pin. Last number means that number four is ground means negative.

Through this world, echo sound will be emitted from a speaker and its speaker will be received by reflecting on an object. The distance is verified by measuring the amount of time Sound will catch through reflecting time.

Two echo sensors used on the circuit, two buzzer and one arduino. See the circuit for more information.
