IO
Two analog inputs which can provide up to 12 bits of resolution
(i.e. 4096 different values). By default, each input measures
from ground to 3.3 volts, though is it possible to change the
upper end of their range using the AREF pin
IO
A0 can also be used as a DAC output and provides a 10 bit
voltage output with
