* In the function call attachInterrupt(A, B, C)
* A can be either 0 or 1 for interrupts on pin 2 or 3.
* B Name of a function you want to execute at interrupt for A.
* C Trigger mode of the interrupt pin. can be:
* LOW a low level triggers
* CHANGE a change in level triggers
* RISING a rising edge of a level triggers
* FALLING a falling edge of a level triggers
*
* In all but the IDLE sleep modes only LOW can be used.
