Hi,
i don't really understand you question, but :
If I write:
Code:digitalRead(4)
I will read the logic value of PIN# 3 ?
-> yes, it is going to return "HIGH" or "LOW"
And likewise, if I write:
Code:analogRead(2)
I will read the analog value of PIN# 3 ?
-> i think that, if it is not a analog pin, it can't work
