I made LiquidCrystal into LiquidCrystal_I2c, and yes the dht.test does work (verify and upload). I'm sorry I didn't realize there was a second page. Ok I fixed the dht library but I still have these errors: Since sketches include paths to the standard library locations, and link the standard library code, you can include the header file for the standard library of interest in your sketch. Sketch_dec26a:59: error: expected primary-expression before '.' token There is a work around, however, for using standard Arduino libraries in your own library that youre placing in your sketchbook/libraries directory.

Sketch_dec26a:13: error: 'LiquidCrystal' does not name a type Creating an Arduino library is a great way to write reusable code for your projects, and also to help other Arduino developers in their own projects. Ok I did that here's my new errors: (the code is the same) This report would have more information with Not used: C:\Users\alkre\OneDrive\Documents\Arduino\libraries\Arduino-LiquidCrystal-I2C-library-masterĮrror compiling for board Arduino/Genuino Uno.

There are 2 errors here - the missing SD library and the missing arduino.h. This is for a different but smaller sketch than I first posted. Multiple libraries were found for "LiquidCrystal_I2C.h" Here is the code and the compiler output.
