Why did I do this?
Ultrasonic Range Finding is something that I am very familiar with because we used the sensors a lot in my electrical classes. Also, I believe that range finding is a very important tool used for things such as building, hunting, sports, etc.
My Plan
The goal is pretty straight forward, you have to build a common ultrasonic rangefinder circuit and then you have to modify the sensor using a blanking circuit in order to reach the maximum range of 9 meters.
