Hi Robert,

Yes with Arduino if you create additional ccp/c/h files you need to manually #include libraries.

Alternatively you can create additional .ino (sketch) source files. You might already know this and have discarded the idea. 

Depending on your point of view, the additional .ino sketch files can be quite useful because they are combined together during compilation so share the same includes, variables, methods etc. Libraries only need to be declared in the main .ino file.

All of this is standard Arduino stuff which means you can also use the arduino.cc wiki, playground and forum where you might get clearer answers.

One question about "double defined". Did you place the .c #include within "#ifndef _SOURCE FILE NAME_h" of the .h?

Thanks

No probs, C++ might be easier than C and .ino files are the simplest. 

Don't forget that all .ino files are combined into a single source for compile. All prototypes are automatically created for .ino files. It is an easy way to keep code organized without needing to worry about libraries, variables, static etc.

Thanks

There are menu items on the project tool bar button and also if you right click a project name in the solution explorer.

Add new sketch source (pde/ino)
Add new c item
Add new cpp item

Hopefully you used the C or the Cpp options when you attempted to add your sources previously. Or you might have discovered you can manually add c/cpp to the project using the standard Atmel or Visual Studio "Add source to project" features.

The 3 options mentioned above are controlled by Visual Micro and provide all the workflows to ensure a valid addition to the Arduino project. 

EDIT: However with ino/pde files there is no real difference to adding a file manually. The way Arduino works is that ANY pde/ino files in the sketch folder are automatically compiled and the Arduino core (api) is automatically included based upon the selected board (micro controller). Therefore, code functions such as millis() are automatically available to all pde/ino sketch sources without the need for #includes.

To answer your question, no you do not have to include the ino/pde files. All of this happens automatically for ino/pde.

One last point for new Arduino users. All the sketch source code must exist in the sketchs' folder. Sub directories with sources are not supported.

Happy holiday

Hi,
I did what you said, and it worked.
But now I have another problem.

I declared my class in Timer.ino:

class _CDimmer : IntervalTimer {
private:
	// Daten
	_Heute Heute;
	elapsedMillis	test;

	// Funktionen
	int getDimmIntervall( int data );
	void getHeute( unsigned int Datensatz );

public:
	_CDimmer();
	~_CDimmer();

	void Setup();
	void Dimmer( void );
} Dimmer; 

but when I want to use it in the main program:

// Objekte
extern _CDimmer	Dimmer;

void setup()
{
	pinMode( PIN_INTERN_LED, OUTPUT );
	digitalWrite( PIN_INTERN_LED, 255 );

	Serial.begin( 9600 );
	delay( 5000 );

	//DisplaySetup();
	//Dimmer_Setup();
	Dimmer.Setup();
	....
} 

I get this message from the compiler:

Am I wrong about classes in arduio?
Or how can I fix it?

Thanks again and happy Holidays
