Great! Lady Ada's software has helped me :) Thank you!
Ok, back to my delay... This is simple code in interrupt (looped):
I have burned bootloader using ATTiny45 @ 1MHz board from:
And then load my app. It's blining 4-5 times per second. With 8MHz it is blinking so fast that I almost can't see it.
The best setting was burning bootloader using 1MHz and then sending application with 8MHz selected - it gave me about 200-500 ms delay with delay(1000).
What am I doing wrong? :)
EDIT: Or maybe not... I'm confused. Every time I'm changing something it seems different smiley
Now it works, thank you again!
