arduino software

#include <interrupt.h>

#include <NewSoftSerial.h>
#include <LiquidCrystal.h>
#include <SoftwareServo.h>
#include <math.h>
#include <EEPROM.h>

Hi, i have a question regarding the arduino software.
As you can see above, i include all the libraries that i need.
But i noticed some are shown in orange, others in black.
Is this normal or does this mean that some libraries cannot be found in the folder?
Because when i compile my code i get no errors.

Notice how only certain words are highlighted and not the “.h”? The highlighting is a result of the IDE editor’s relatively simple syntax highlighting. The words in Orange are known and have other functions. In this case, it has nothing to do with being libraries.

thank you for the info :slight_smile:

keywords.txt files are missing for unhighlighted libraries. You can easily create the keywords.txt files. After creating the files restart the Arduino IDE.
