Writing the signature bytes.
99% of the "my chip doesn't work" complaints always end up as "user error". So I start out with assuming that I've done something wrong.    In this case, I asked...

Writing the signature bytes.
yes. I use avrdude, so -F is the option to override the check for the correct signature.    It is not really important  to write it correctly. With the chips...

Capacitor on AREF of ATmega328.
Quote:Data sheet says AREF input resistance is 32K ohms. Yes, the input resistance of AREF is specified. Now the output resistance of the 1.1V reference signal.... @david....

Input impedence
Note that the ADC input is not static. During the sampling it will pull some current from the source signal, and then it will be high impedance for a while. So the behaviour of...
