Me bad, I think I changed some code to work with Arduino 17, all I did was changing the old Serial syntax to the new ones.
What Arduino board are you using? I tested all the code, and Arduino02 does NOT give an error here when compiling. What error message do you get? You should copy the code from the page, not from the package.
I think the patches are getting screwed because you have an EMPTY slice in there at startup. The S+H nodes are slightly changed. With Herr Inspector, you can change the toggle called ‘set on create’ and than save the patch and re-open it.
For Arduino05, the one with firmata, I don’t know/do that, it says it is an implementation of it, and the final version will be different, so I think they changed it.
