hi all,
i have measured pins analog outputs with voltmeter, and found that majority of them works in quite strange way. i have set analogWrite(ledPin, 127)
and expected to see ~2.47V, but i found that a lot of pins are showing 0V.
does it mean that i damaged iternal resistor, or other component in arduino?
what are you thinking? :-/
to explain more clearly, i want to mention that in fading example, one one pin just blinking - when output sets on 100, LED turn on, and LED tunr off, whet it above 100.
it's confusing me 
Only certain digital pins can perform analogwrite, they are the pins that have PWM capabilities.
Also not being a true analog output voltage but rather a pulse train with variable duty cycle a DC volt meter won't respond accurately at all. A scope is the best instrument to see the waveform.

whuh! thank you for respond
sorry, i should RTFM first:}}}
that's what i found in diecimila description:
PWM: 3, 5, 6, 9, 10, and 11. Provide 8-bit PWM output with the analogWrite() function.
