Arduino has three different sources of Interrupts: Timer Interrupts External Interrupts Pin-Change Interrupts NOTE: Timer Interrupts in Arduino, as the name suggests, are caused by the Arduino Timers while the Pin-Change Interrupts can be enabled when a change in state of a group of Pins is detected.

This example doesn't take that into account. One gotcha with this simple example is that push buttons tend to bounce, meaning that when pressing or releasing, the circuit opens and closes more than once before it settles into the final closed or open state. ![]() ![]() note: LOW = false = 0, HIGH = true = 1, so inverting the boolean is the same as switching between LOW and HIGH. const int LED_PIN = 13 ĪttachInterrupt(digitalPinToInterrupt(INTERRUPT_PIN), myISR, FALLING) // trigger when button pressed, but not when released. This example uses a push button (tact switch) attached to digital pin 2 and GND, using an internal pull-up resistor so pin 2 is HIGH when the button is not pressed. ![]()
