Is there a false positive in Arduino includepath?
However it builds/uploads and runs perfectly well, it also finds the classes etc. defined in said includes so it looks like it’s a false positive in some way (i.e. the path is included in includePath settings). Reading the error message also shows it having issues finding a header referenced in Arduino.h called “avr/pgmspace.h”.
Is there a library for the Arduino 4×20?
I’m trying to start with the SainSmart 4×20 serial LCD, and copied the library to the Arduino library: So LiquidCrystal_I2C.h is included.
Why is my library not loading on my Arduino?
Do not omit or alter the names of any files inside the library folder. The IDE will not load files with certain characters in the name. Unfortunately, it doesn’t like the dashes in the zip files names generated by Github. When you unzip the file, rename the folder so that it does not contain any ‘illegal’ characters.
Why is keyboard.h not included in Arduino?
Keyboard.h is already included as a default library in Arduino so I’m not sure what’s wrong If you have Arduino/Genuino Uno selected as your board in the Tools ► Board ► menu, then you get the error. If you select Arduino Leonardo it compiles correctly.
Where is the library folder on an Arduino?
The actual library folder is a folder within the top-level repository folder. It is there. But on a Windows or Mac/OSX machine it may not be named “Sketchbook”. See the page titled “Where to Install your Libraries”. You must download and install the entire library. Do not omit or alter the names of any files inside the library folder.
