The Quorum Studio Coding window for this lesson appear here with the lines of code and comments. Look for links named Full Code as Text with Comments to get the same information in text.

UltraSonic16 this code is like the last lessons but it adds sound and screen to your code. You will also learn to display data from the sensor. You also will be using a compute.math libary for the first time.
