I see... thanks for putting the comments in.
That part of code is from the Wave shield code and I didn't change it.
Maybe if you or someone who has the time and patience can take a look at the two sketches separately and come up with a way to get the IR senor results to trigger waves.... I am really not fluent in c++ coding at this level to make this work, so please help if you can!
