   1 /* Software voltage regulator using analog read and PWM
   2    Connect both voltage sensor and output pin to possitive side of capacitor
   3    Then connect negative side to ground
   4    Voltage should be approximatelly stabilized at AREF/2
   5    You can use some push-pull (totem pole) kind of buffer at output pin to supply more current
