In the case of that library it is actually buried in the .h and .cpp files themselves. Version 1.1 is wat I found in those files. I have never used the library you point out, but the one that was originally used for the video Bill produced. That library has been relocated to GitHub at: New-LiquidCrystal Library

Thank you very much codecage. I cleared my library of existing liquidCrystalI2c libraries and went to GitHub downloaded the zip file, and lo and behold it worked. The LCD_liquidCrystal_demo 2018 now verifies

I have reviewed the original video "Using LCD Displays with Arduino" and in it Bill does say to use the NewLiquidCrystal library for I2C from github.com If I had done this in the first place I would not have had all this trouble. I do not know where the LiquidCrystal library that I had installed came from but it worked on other projects so I assumed it to be ok. I have an existing stop watch that uses the library it is fine as the program does not contain that "POSITIVE" command.

I was determined to succeed after devoting so much time to it, but I still do not know exactly what the "POSITIVE" command does. The same command also appears in the Temperature & Humidity Gauge sketch.

If I remember correctly it controls whether the back light is on or not.

I am totally new to arduino and C actually. I am in the progress of collecting basic hardware to begin experimenting. I am currently trying to connect an LCD 19264 to an I2C expander I found on ali.
I ran into some problems, so I will post the spec here to see if you guys have any suggestions. I did solder everything together without taking any closer look. I can see now there are some differences in the boards..
Thanks 🙂
