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