Dear Sir/Madam  
I followed the instructions provided through the Sloth SunFounder STEM EDUCATION manual but the Test for Servos and Ultrasonic Module failed. It appears the failure is related to the error message “compilation error: NewPing.h: No such file or directory”. Please see attached snapshot describing the problem in more detail.  
I would appreciate your assistance in this matter.

Please see the screenshot.  
First click on the project, select Add File, go to the “NewPing.h” path and open the NewPing.h file.
