i face this error and i tried much of solutions i found in google and still not work
C:\Users\l0l0-\AppData\Local\Temp.arduinoIDE-unsaved2024114-12824-k8zcq7.aos2g\sketch_feb14a\sketch_feb14a.ino:2:10: fatal error: OneWire.h: No such file or directory #include <OneWire.h>
^~~~~~~~~~~
compilation terminated.
exit status 1
Compilation error: OneWire.h: No such file or directory
now i'm trying another library and gives me the same error. I'm trying to write a code for pulse sensor and try every solution i know and still not workin
Unfortunately there is a bug in the sketch compiler that causes it to fail to find the library when it is installed under a path that contains this sort of character:
The presence of such characters in the path is more likely to occur because Microsoft OneDrive automatically uses the localized name for the Windows Documents folder based on your system locale.
The workaround will be to configure Arduino IDE to use a different path to store libraries. I'll provide instructions you can follow to do that:
Select File > Preferences... (or Arduino IDE > Settings... for macOS users) from the Arduino IDE menus.
The "Preferences" dialog will open.
Click the "BROWSE" button on the right side of the "Sketchbook location" field.
The "Select a new sketchbook location" dialog will open.
Select a folder in any location that contains only basic ASCII characters (the characters A-z, 0-9, _, -, . are safe).
Make sure to pick a location that will be safe to store your files since, in addition to containing installed libraries, the sketchbook is a convenient location to save your sketches.
Click the "Choose" button in the "Select a new sketchbook location" dialog.
Click the "OK" button in the "Preferences" dialog.
Move all the files from the folder at the path of the old sketchbook location:
C:\Users\l0l0-\OneDrive\المستندات\Arduino
to the folder at the path of the new sketchbook location you set in the Arduino IDE preferences.
Once you have finished performing the instructions above, try compiling your sketch again. Hopefully the compilation will be successful this time.
i write a code to find the SPO2 and HR from HRM2511E sensor but it gives me an error:
C:\Users\l0l0-\AppData\Local\Arduino15\RemoteSketchbook\ArduinoCloud\107194317737973883191\new_sketch_1708247243703\new_sketch_1708247243703.ino:3:10: fatal error: MAX30100_PulseOximeter.h: No such file or directory #include <MAX30100_PulseOximeter.h>
^~~~~~~~~~~~~~~~~~~~~~~~~~
compilation terminated.
exit status 1
Compilation error: MAX30100_PulseOximeter.h: No such file or directory
This error indicates that you haven't installed the library that contains the MAX30100_PulseOximeter.h file.
Please provide a link to where you found this code. That will likely give us the context we need to provide you with the appropriate instructions for installing the missing library.
Ask ChatGPT how to install the library. Hopefully it will know the answer. If not, let us know and we will take a guess at which library it intended (it is hard to be certain because sometimes there are multiple Arduino libraries with a header file of a given name, but different APIs).
I'm going to ask you to post the full verbose output from a compilation.
This procedure is not intended to solve the problem. The purpose is to gather more information.
Please do this:
Select File > Preferences... (or Arduino IDE > Settings... for macOS users) from the Arduino IDE menus.
The "Preferences" dialog will open.
Check the box next to "Show verbose output during: ☐ compilation" in the "Preferences" dialog.
Click the "OK" button.
Select Sketch > Verify/Compile from the Arduino IDE menus.
Wait for the compilation to fail.
You will see a "Compilation error: ..." notification at the bottom right corner of the Arduino IDE window. Click the "COPY ERROR MESSAGES" button on that notification.
Open a forum reply here by clicking the "Reply" button.
Click the <CODE/> icon on the post composer toolbar.
This will add the forum's code block markup (```) to your reply to make sure the error messages are correctly formatted.
Press the Ctrl+V keyboard shortcut (Command+V for macOS users).
This will paste the compilation output into the code block.
Move the cursor outside of the code block markup before you add any additional text to your reply.
Click the "Reply" button to post the output.
In case the output is longer than the forum software will allow to be added to a post, you can instead save it to a .txt file and then attach that file to a reply here:
Open a forum reply here by clicking the "Reply" button.
Click the "Upload" icon () on the post composer toolbar:
The "Open" dialog will open.
Select the .txt file you saved from the "Open" dialog.
Click the "Open" button.
The dialog will close.
Click the "Reply" button to publish the post.
Alternatively, instead of using the "Upload" icon on the post composer toolbar as described in steps (5) - (7) above, you can simply drag and drop the .txt file onto the post composer field to attach it.
I have merged your topics due to them having too much overlap on the same subject matter @lujain_xx.
In the future, please only create one topic for each distinct subject matter and be careful not to cause them to converge into parallel discussions.
The reason is that generating multiple threads on the same subject matter can waste the time of the people trying to help. Someone might spend a lot of time investigating and writing a detailed answer on one topic, without knowing that someone else already did the same in the other topic.
