user71260: PID library is available(built in) in standard installation  of arduino IDE or do we have to download it additionaly after installing our IDE?
How can i check which of libraries are available in my standard installation?

user7508: Open the Library Manager and search for the library you want. You will
see a list of libraries matching your query. Under the name of each of
those libraries, you will see a line showing the author and the version
number.

if this lines stats with “Built-in”, then it is a library that comes
with the standard installation of the IDE

if the line ends with “INSTALLED”, then this library is installed in
your system.
