Several people have asked about the DC accuracy of the Arduino ADC when used in my data logging applications at slow sample rates. Here are my results of some "hobby level" measurements of the Arduino ADC. One question is how important is the ADC clock rate. I did measurements for an ADC clock rat…

Oops. Looks like I'm rather out of date on how these things are constructed. Thanks for the correction.
