Fatal error: BH1750.h: No such file or directory

[pollos]

I keep on getting this error

sketch_dec05a.ino:8:20: fatal error: BH1750.h: No such file or directory
compilation terminated.

I've gone to sketch > Import Library and BH1750 is listed.

Is there anything I can do to fix this?

This is the code:

Where exactly is BH1750.h located on your PC ?

[pollos]

It's located in Arduino libraries folder and another folder

please RE-edit your posting to present your code as a code-section

click on the pencil-icon below your posting and then re-edit your posting following this short tutorial

Make experienced users help: two ways to quickly post code as a code-section

Hi newcomer, This thread wants to show you how you can speed-up getting helpful answers with small effort. If you manage at least to post this way. You have the sympathy of the experienced users. If you are willing to invest another 20 minutes these 20 minutes extra-time will save you a minimum of 200 minutes to finish your project. always post your full sketch. As a code-section from the very first to the very last line A code-section has a small height => keeps your posting "short" but…

None of those locations look correct.

The .h and associated library file should be in a folder in the libraries folder of your Sketchbook folder. By convention the name of the folder would be BH1750

How did you install the library

[pollos]

I do have a folder called BH1750 in my home/user/Arduino/libraries folder.

I downloaded it as a ZIP file from onedrive then on Arduino IDE I went to Sketch > Import Library > Add Library and then imported the ZIP file.

[UKHeliBob]

That folder does not seem to be in your screenshot

[pollos]

Sorry, that's because I looked up with the .h specifically

Here is a screen shot of just BH1750

[UKHeliBob]

@pollos

I looked up with the .h specifically

Then why did the home/user/Arduino/libraries/BH1750 folder not appear in the search results ?

Please post a screenshot of the contents of the home/user/Arduino/libraries/BH1750 folder

[pollos]

I don't know why that could be.
These are the contents of the home/user/Arduino/libraries/BH1750 folder

[UKHeliBob]

What is in the src folder ?

[pollos]

A .cpp and .h of the Bh1750

We have to check where your arduino-IDE is looking for the file.
There might be still something wrong with the place where the library is stored.
To find out if this is the case

You are working with a MAC but I think the same steps can be used to maximise the compiler-log-info.

If you get a compiler-error provide all details for analysing the error

Hi newcomer, the Arduino-Forum community can be of great help. If the community is able to support you in a way that helps solving your problems depends on detailed information that you should provide. trying to be quick by posting a too short posting is just slowing down finding the solution. Because all that happends is that you are asked for the detailed information and have to provide it anyway. Only difference the answer and the solution comes later The most important thing is to pos…

If you got the aborted compiling
post the compiler-log as a code-section as described in this tutorial.
