WebIf one of the buttons is pressed one led will blink for 10 seconds, pressing the button mid blink will extend the time the led blinks by another 10 seconds. Whilst this is happening if you press the second button the other led will turn on, but only when the button is pressed. Using delay () to achieve this would not work nearly as well. WebJul 24, 2024 · What Arduino libraries do with the priorities when two pins in the same group are triggered at same time can be read from Arduino code or documentation, it has nothing to do with the AVR chip itself. Edit: It seems that the Arduino function you use only supports EXTI0 and EXTI1 interrupts, not pin change interrupts.
