Ultrasonic wave
meter
We are used to say that bats are blind... but bats see at night! This project will use ultrasound to get the distance between the sensor and an obstacle. This allows the use of this project in automated systems such as robotics or home automation systems. The application also shows the versatility of Freedom embedded system to which we must just connect an ultrasonic sensor and an LCD, for which already has the sockets.
