'''
The irq() method accepts the following arguments:

trigger: this defines the trigger mode. There are 3 different conditions:
Pin.IRQ_FALLING: to trigger the interrupt whenever the pin goes from HIGH to LOW;
Pin.IRQ_RISING: to trigger the interrupt whenever the pin goes from LOW to HIGH.
3: to trigger the interrupt in both edges (this means, when any change is detected)
handler: this is a function that will be called when an interrupt is detected, in this case the handle_interrupt() function.
