Using Arduino 1.8.12 and the code from this link

I get the following error message:

Hello!

It looks like you need the most updated version of the GraphicsBuffer library: https://github.com/TinyCircuits/TinyCircuits-GraphicsBuffer-Lib

The line follower sketch still does not compile using the latest graphics lib you linked to.

I think I need to delete one or more of the libraried I have installed to get the right font.h.

Here's what I have in my libraries folder:

Hmm. It's possible you have an older version of the TinierScreen library too?

I have both libraries and they both have a font.h file and I am able to compile and upload the programs to a RobotZero. The only difference I see between us is my master files are just named GraphicsBuffer and TinierScreen in my library directory. You could try re-downloading the newest version of TinierScreen from the GitHub page: https://github.com/TinyCircuits/TinyCircuits-TinierScreen-Lib

Hope that helps!

I was FINALLY able to get this to compile by performing the following steps:
