Aref arduino - Arduino Glossary
analogReference() Description the default analog reference of 5 volts (on 5V Arduino boards) or 3. 3 volts (on 3. 3V Arduino the voltage applied to the AREF pin.
I am working on a project that uses an LCD shield, and a thermistor. My problem is that the lcd appears to be using the AREF pin, but my
ATmega328 Analog Inputs. What are the AVCC and AREF pins for? They are support for the ADC system in the ATmega or ATtiny. If you are trying to get accurate readings.
