RISING and FALLING interrupt on same pin?

Thats badically it, the external interrupts int0 and int1 which are on digital pins 2 and 3 can be set to interrupt on rising, falling or change which is the one you want.

For the other interrupts its a little more difficult, but there is a library that helps. here is a quick overview of the library 'pinchaneint'
