This report would have more information with "Show verbose output during compilation" option enabled in File -> Preferences.


This may be a problem with the library reference,

The error is related to the keywords “undefined reference to”,

You may also find help by searching on Google for “arduino undefined reference to”:

Maybe this might help:

You shouldn’t need to do this:

#include <…\libraries\TimerOne\TimerOne.h>


#include <TimerOne.h>


You might have an incorrectly installed library or you have an example installed in the libraries folder. Please post links where you found the code.


You shouldn't need to do this:

Something like that can be required when you have a library installed in the src directory of your project. In that case one includes like below

#include "src/myLib/myLib.h"
