Welcome to the Distance-measurement!
In this Project we have measured the distance using Ulta-Sonic sensor(HC-SR04) which is controlled by FPGA Board. The distance is displayed on 2 digit 7-segment display.
In this project interfacing of ultrasonic sensor with FPGA first we need to understand the working of ultrasonic sensor HC-SR04. This device is basically send the ultrasonic wave and whenever any object comes in its way it will be reflected back and received.
The device contains 4 pins
