Hi
Is it possible to add more interrupt pins for clock on an arduino uno? If so how would that be done?
On the Uno you have two direct interrupt pins, D2 and D3 which correspond to attachInterrupt (0, ...) and (1, ...)
However there are also three "pin-change" interrupts you can use that monitor changes on whole sets of pins - search for "pin-change interrupt" or PinChangeInt
Why do you think you need more? What are you trying to do with them?
