AVR-Chat

Hi Tom - Not all the guys in the group will agree, but i'm still
old-school. I like doing my debugging with a "real" chip and "real"
led. But basically don't lose hope ! EVERY time that something in the
AVR have not done what they were supposed to, it was my software that
was at fault.

As many other have suggested: Make sure global interrupts are enbaled,
make sure the timer interrupt in TIMSK is enabled, make sure the timer
is set to run (usually in TCCR1B etc), make sure an interrupt can
happen (ie. if you using an overflow interrupt, make sure the timer is
not configured for CTC with a value less than the overflow value etc.)
The only other thing I can recommend is actually programming a chip
and getting a scope and some leds out to debug what is happening.
