Going to start off stating that I'm NEW to this. I'm looking at the NERDKIT demo for Temp sensor, and I cannot figure out what code actually links the ADC to PIN 23 (PC0/ADC0). I guess my question is if I wanted to measure something else as well how could I point my code to the next pin (ADC1 or ADC2)? Sorry if i'm asking a stupid question but got to learn some how.

Hi John,

You want to look at the ADMUX register to multiplex between the different inputs to the ADC. This forum post goes over how to sample from different analog signals.

Thank you I think thats what I want.

So to recap I would change: ADMUX = 1; or ADMUX = 2;

• Thank you JOHN
