BEG281 Optical Fingerprint Reader library

Someone help me with BEG281 Optical Fingerprint Reader library please

?

You’re very unlikely to get any help for such a vague request.

Post a link to where you got the library from. Please use the chain links icon on the toolbar to make it clickable. Or if you installed it using Library Manger (Sketch > Include Library > Manage Libraries) then say so and state the full name of the library.

Provide a detailed and complete explanation of the problem you’re having, including complete code and any error messages you’re getting.

If possible you should always post code directly in the forum thread as text using code tags (</> button on the toolbar). This will make it easy for anyone to look at it, which will increase the likelihood of you getting help. If the sketch is longer than the forum will allow then it’s ok to add it as an attachment. Don’t put your code in some external file service like dropbox, etc. We shouldn’t need to go to an external website just to help you. I do feel it’s reasonable to post a link to code hosted on GitHub or similar code hosting sites since that’s an platform specifically designed for this sort of thing

Please always do a Tools > Auto Format on your code before posting it. This will make it easier for you to spot bugs and make it easier for us to read. If you’re using the Arduino Web Editor then you will not have access to this useful tool. I recommend using the standard Arduino IDE instead.
