The library was downloaded using the download link on the default library, MemoryFree, using the Arduino Web Editor. It doesn’t provide a link. It just pops up the Windows File Manager to query me on where to save it.
I found it odd that I had to download a default library, MemoryFree, to use it, but followed your instructions to download and then import it, and it solved my original problem of not finding MemoryFree.h. However, now when I use the SEARCH libraries function it now displays 2 versions of the MemoryFree library. Just thought I’d mention it in case it’s relevant.
Here is the error output: (I didn’t include the compiler output that worked. Let me know if you need it)
Using library MemoryFree at version 1.0 in folder: /tmp/155276773/custom/MemoryFree

exit status 1
