Liquid Crystal Sensor

I am ready to pull my hair out! I have tried everything that I know of, and I still cannot get rid of “No such file or directory”. I am new to Arduino. Would someone please help me?

Would someone please help me?

We would if we knew what you were trying to do. Post the code that you are having trouble with. Read the how to use this forum-please read sticky to see how to properly post code and some advice on how to ask an effective question. Remove useless white space and format the code with the IDE autoformat tool (crtl-t or Tools, Auto Format) before posting code.

It is almost certain that you are trying to #include a library that is not properly installed on your system.

We are glad to help, but we are not psychic. We have to have something to go on.

You have to place the missing file where it's expected to be.
