We wanted to use a sketch from the internet, but the libary is deprecated. When replacing the the new library in the '#include <>' , some things are not declared in the scope of course. If import the old library, the zip does not contain a valid library. Do you have an advise how to solve this?
I need more information... What sketch from the internet? What library?
For the MP3 module you borrowed from me, you just need the DFRobotDFPlayerMini library, as used with the example.
It's about this sketch in the comments: https://www.youtube.com/watch?v=qRReVUE_Vcc. It contains: #include This library is deprecated: https://github.com/DFRobot/DFPlayer-Mini-mp3 and the new library is not recognized.

Ok. I got it. But why would you use an old example with an old library when there is a better, newer one?? Did you have a look at the examples of the new library? Like this one? – Fjodor van Slooten Jun 9 at 10:14
