Read Pattern Data pada Digital Input Arduino UNO

[kolaha]

yes, but what is able to read consecutive periods?

UPD;

RISING and FALLING interrupt on same pin?

I realised a routine for starting an exposure timer, which has a single start button at INT1 and the same button should be used to store permanently the selected time (set by a rotary encoder on the remaining pin INT0) into the EEPROM for further usage, if found worthwhile. Depending on the duration time the button is pressed, different actions will start accordingly. During these activities the interrupts are temporarily blocked from being interrupted by other interrupts. Here is what I did t…
