Library properties

Hello all. I'm trying to upload a library file and I'm getting the following error code when I try to upload a zip file into the library. I'm using the Arduino cloud so how do I fix this issue?

Can you share the path to the library?

Hi @rkelso. Unlike the Arduino IDE, Arduino Web Editor requires all libraries to contain a library.properties metadata file. In order to import this library into Arduino Web Editor, you'll first need to add this file to the library. You can do that by following these instruct:

Unzip the library's .zip file.
Delete the library's .zip file.
Create a file named library.properties in the library's root folder.
Open the library.properties file in a text editor.
Add text to the file following the Arduino Library Specification:
https://arduino.github.io/arduino-cli/latest/library-specification/#libraryproperties-file-format
Don't worry too much about exactly what you fill the fields with, it's mainly just the presence of a valid library.properties file that's important.
Save the file.
Zip the library folder.
Import the .zip file in Arduino Web Editor.

Please let me know if you have any questions or run into any problems while following those instructions

OK, got that one fixed and moving on, now I'm getting this... I have verified 0x27 is the correct address.

This error is caused by using a different "LiquidCrystal_I2C" library than the one your sketch code was written for. Unfortunately, there are multiple libraries which contain a LiquidCrystal_I2C.h file and they have incompatible APIs.

I'm going to ask you to post some additional information that might allow us to provide you with instructions for fixing this.
Please do this:

From the menu on the left side of the Arduino Web Editor window, click "Preferences".
Check the box next to "[ ] Always show output panel".
Check the box next to "[ ] Console: Show verbose output".
In the sketch pane, click the (verify) button.
After the compilation fails, click the icon in the top right corner of the black console window at the bottom of the Arduino Web Editor window that looks like two pieces of paper.
In a forum reply here, click on the reply field.
Click the </> button on the forum toolbar. This will add the forum's code block markup (```) to your reply to make sure the compilation output is correctly formatted.
Press Ctrl+V. This will paste the compilation output between the code tags.
Move the cursor outside of the code tags before you add any additional text to your reply.
Click the Reply button to post the output.

Here you go. I deleted the Liquid Crystal file and downloaded one from the LCD manufacturer. It will properly display an example "hello file" but when I put in my program, it doesn't work, just a blank screen. It's odd that it works in one program but not the other.
