PWR_DOWN & external interrupt


Good enough.
Because at the end of the day, Arduboy is rechargeable.
I am aiming for it to go three days (because you either play it in three days or turn it off and leave it aside, and clearly you guys did good job.
@Mr.Blinky, thanks for your code.


Don’t know why I missed this before but the B button can wake up Arduboy too by making use of the pin change interrupt. I’ve updated my powerdown demo so you can use both A and B button to wake up Arduboy :smiley:
