not work properlyis the timing. The bounce library use millis(), and if you choose
for example the board: Attiny85@8MHZ without setting the right fuses, the timing will be off by a factor 8.
The factory default is 1MHz, so unless you have set the fuses yourself you should choose Attiny85@1MHZ
If you want to run 8MHz, do this:
Select Board -> Attiny85@8MHZ
select Programmer -> Arduino as ISP (or watever programmer you are using)
Select ->Burn bootloader
I'm not sure that all the code is supported by the attiny85
