faekeid:

Are you compiling a program?
Hooking it up?
Sunning yourself?

Do you have code to post?

Should we just guess about everything?

See the # above? Push it --- see the Two cross-hatches?

Copy your code and paste it in between them.

If you are going to use a "fakeid" can we give fake answers? :grin:

Does an empty Sketch compile...

void setup( void ) { }
void loop( void ) { }

Does this compile...

void setup( void )
{
  Serial.begin( 9600 );
}

void loop( void ) { }
