How many analog pins on an Arduino Uno board?

Knowing how many analog input pins a standard Arduino Uno provides. The Uno has six analog inputs, labeled A0 through A5. These connect to the six ADC channels of the ATmega328P microcontroller, enabling 10-bit conversions via analogRead(). The typical reference is 5V, so a reading of 0 corresponds to 0V and 1023 corresponds to Vref. While these pins can also be used as digital pins if needed, there are six dedicated analog input channels.
