Ultrasonar

This project emits ultrasonic waves to the target then receives the reflected waves. This will give an idea of what the distance is between the target and the source. The servo motor will help to scan the area for the wider cover in one axis only. The host microcontroller will compute for the distance and then send to the display. The gen4 display will plot the data on the screen.
