I have never had any trouble with the standard Liquid crystal library that I have been using successfully, however, I need to install the I2C Liquid crystal version.
From https://bitbucket.org/fmalpartida/new-liquidcrystal/downloads and selected LiquidCrystal_v1.2.1.zip
I then went to my sketch and then Include Library - Manage Libraries - Add .zip Library - Downloads - LiquidCrystal_v1.2.1.zip and then checked open.
When I run my test sketch I get an error message: C:Users\User\Documents\Arduino\libraries\LiquidCrystal\I2C_ID.cpp:5:26:fatal error: /Wire/Wire.h: No such file or directory.
My sketch includes Wire.h so ????
Should the library be in the Arduino Program File (x86) or in the Documents Arduino folder?
I have tried to follow the procedure in learning "Installing Additional Arduino Libraries"
I must be doing something fundamentally wrong!
