WebDigital Pins With Interrupts. The first parameter to attachInterrupt () is an interrupt number. Normally you should use digitalPinToInterrupt (pin) to translate the actual digital pin to the specific interrupt number. For example, if you connect to pin 3, use digitalPinToInterrupt (3) as the first parameter to attachInterrupt (). Board. 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.
