Hi,
I have a push button, and i want to connect to a microcontroller, and i have two actions :
--long press
--short press
can i do this by only microcontroller and puch button ?
thanks
 

Yes. Connect Push button to an Interrupt pin (To avoid polling overhead). Start a timer upon interrupt. Use the timer value to determine whether it is a long/short press.
 

can the timer, count till 3 second ? and 5 second ?
