but i can't program one like this(can't read two pins and get the temperature from them),
i can't deal with two pins of ADC, i only can deal with one pin. so could any one teach me how this circuit work?, how to program these two pins ?and what happens inside the ports when i deal with two pins instead of one?, and how to measure the value of the sensor?. BTW, i'm studying from a book but the book didn't say any thing about this, i searched a lot but i need direct help. thank you.
