Using LCMI602 IIC VI with Photon

Hey guys, newbie here. Thought I’d get started using and LCD with some hackster projects. Followed along this tutorial.

When I try to compile the program however, I’m faced with a whole bunch of errors that seem to be focused on components from the library.

I tried another project the clock code and I was faced with a ‘pins_arduino.h: No such file or directory’ error. What am I missing?

Thank you for your contribution in this forum.
