I am trying to install the Teensy loader software but I need to know where Arduino is installed. Does anyone know where in Fedora the Arduino files are?

It depends how you installed it.

If you downloaded the tarball and extracted it then it's wherever you extracted it.

If you used a package manager to install it then they could be anywhere - you should look at the package manager software fedora uses (yum? it's been a while) to see how to find what files a package installs.

If you are running a modern version of Arduino (I know Debian based packages are from the stone age) then the board manager installs will be in ~/.arduino15


Assuming you have installed the tool from the Fedora repositories (that is, using yum/dnf or from the Software tool), the command to run the IDE will be installed at /usr/bin/arduino and you can run it from the command line just by typing arduino — or do the same in the search box in GNOME Shell.

Most of the package itself, including examples and libraries, will be installed under /usr/share/arduino.

And, once you run that program, it will create a new "sketchbook location" at ~/Arduino — that is, a folder named "Arduino" in your home directory. If you've run the IDE already, that folder will already exist.
