Dead link + some questions

[bartgrefte]

Hi Peter,

I just came across https://github.com/petervojtek/diy/wiki/Arduino-with-Very-Low-Power-Consumption where I noticed a dead link in this sentence: "The battery voltage is measured using Atmega328's internal 1.1V reference voltage." https://github.com/petervojtek/diy/wiki/code.google.com/p/tinkerit/wiki/SecretVoltmeter doesn't work, I believe it should be https://code.google.com/archive/p/tinkerit/wikis/SecretVoltmeter.wiki

And after looking at the Fritzing picture, I'm a bit confused:

• the code says the led is on pin 13, but on the Fritzing picture, it's on pin 19. Is that correct? edit: Oh wait, pin of the package is not the same as the digital pin numbers....
• the cheaper kit comes with 2 22pF capacitors, looking at the Fritzing picture I see 3 and the 3rd one is hooked up to AVCC. Does AVCC require a capacitor? Not that it's a problem, I believe I've got plenty lying around somewhere.

Thanks for the howto by the way, I think I'm gonna use it for a little project :)
