power down mode and port pins no matter what, the LED is going to be using current if it's on, no way around that. Using 2 pin won't change anything at all. The only option not mentioned is to run the LED at...

avrdude on 64-bit XP Why don't you try it and let us know? It works in 64-bit Vista with one change made by MadWizard.

8-bit music? yeah, there are a lot of headphones ranging from 32 ohm to 600 ohm, I was just saying that the standard, cheap headphones are 16 ohm.

8-bit music? Most headphones are 16 ohm nominal impedance, so they need a halfway decent amount of current.

8-bit music? Simple headphone amplifier that could be driven by an AVR. Doesn't solve the other issues, but it's something.

Well, a 3.7V battery (assuming lithium) can give you...

PIN change interrupt You missed a few steps there. Declare a global variable volatile, then read the pins into that variable BEFORE the cli() somewhere, I would do it before the while loop. Then you...

tweety_bird, all of that should be explained in the link that clawson gave you.

Shouldn't it be TIMSK1 instead of just TIMSK?
If you're using GCC, check out this thread, especially Part 5: https://www.avrfreaks.net/index.p... Otherwise, tell us what you're using.
