    Hi,

    For an AVR, if I set the interrupt to detect a rising edge. How does the uC determine that it has received a rising edge ?, is there some sort of threshold voltage that it uses ?. Likewise for a falling edge,

    Cheers

    The circuit is called an edge detector, and they work quite well.
