+If you're using a recent version of the mbed lib (right mouse button, update in the online compiler):
 Every unique numbered pin. That means you can use any pin as InterruptIn, but you cannot use multiple
 pins with the same number on a different port as InterruptIn. So you can use PA_1, PB_2, PA_3, PC_4, etc.
 But in this example you could not use also PE_1. */
