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.

    I'm voting to close this question as off-topic because the problem is the poster's lack of basic programming skills.

    If the OP has a basic lack of understanding of programming that is a valid topic for them to post about and request help. Aug 7, 2017 at 12:52
  • @CodeGorilla. From Help Center, What Are Off-Topic: "Off topic: If your question is about coding not related to Arduino, try Stack Overflow. If the solution would be the same with or without Arduino, then it's usually a general coding question."

  • @LookAlterno - I understand why you say that, but this is about the inability to find a file, which is an IDE setup issue. Also I suspect the your original answer may have lost something in "translation", because it comes across quite elitist, which I'm sure is not what you meant. Aug 8, 2017 at 12:13
  • @CodeGorilla. I feel this "elitist" thing is something worthy of discussion in Meta. I have already touch the subject in Meta, without any response. Have a look at my answer in arduino.meta.stackexchange.com/questions/2459/…

Please learn how to install a library from here. And see if error is coming or not.
