I have problems with lesson 17 and 18 in Raphael kit. I think its the liberary ADC0834, the compiler writes that it is shadowing? I use the rasberry kit.  
any suggestions?  
thanks in advance

1. What issues did you encounter when running Lesson 17 and Lesson 18? Did you experience any errors when running the code? If so, please provide a screenshot of the error, so that we can analyze and help resolve the problem.

2.Please carefully check the wiring to ensure it is correct. The ADC0834 module has a specific orientation when connecting it to the breadboard. You can observe the lettering on the ADC0834 - the orientation is correct if the letters are facing you.
