No such file or directory compilation terminated I tried a simple blink for my fingerprint sensor which is GT-511C1R, but I have experienced of having an error.


  FPS_Blink.ino:12:26: fatal error: FPS_GT511C1R.h: No such file or directory
  compilation terminated.


I downloaded the whole library but still same error.
Please learn how to install a library from here. And see if error is coming or not.
