Hi, Working with Arduino somtimes it is hard to include a library.
I found out that I have libraries saved on varius places. There are many (but not all) libs in folders there where Arduino is installed, that is standard on my PC C:\programms\Arduino, there is a file called libraries. There are many.
The Sketchfolder is somewhere else, C:\Users\Name\Documents\Arduino, there are Folders with sketches. Thereis also a folder called libraries, that Arduino generated itself, it contains many but not all libraries.
And sometimes I had libraries in the Sketchfolder, they sometimes got included automatically, and working with no problem.
Often I get warnings, stating "libraries in multible places.
Where should the libraries be? So that they show up in the IDE ?
many thanks for any advice, John
