[Icc-avr] Software Delay

[John Baraclough]

Debouncing inside an interrupt is a very bad idea. You should either use 
edge triggering on INT1 or a software debounce that isn't in an ISR. 
There's a lot of good stuff about debouncing in Jack Ganssle's article 
which you can find here <http://www.ganssle.com/debouncing.pdf>.

All the best for now,
John
