sorry for the code tags, and i connected the interrupt pin (pin2) to 5v, this is like a sensor signal i think ,so why does not activate the interrupt ???
and the led is on pin10
Do you know if the LED actually works? It starts off LOW.... if it's faulty then it might be trying to go on when you apply the interrupt but you can't see it.
Maybe change the line volatile int state = [glow=yellow,2,300]LOW[/glow]; to volatile int state = [glow=yellow,2,300]HIGH[/glow]; so it starts in the "on" state and you'll be confident it actually works.
if I connect the ground to pin2 the state of LED changes or just connect a wire to pin2( i dont know why) , but if a connect 5 volts and back nothings append .....
and now I'm testing on RISING mode
is it clear? maybe my English is another problem xD
