CvSeq.h

/*
  CvSeq.h - Library for running a cv sequencer

  The Circuit:
    * Input - 2x 4051 multiplexer 8x 10k pot each
    * Output - 2x 4051 multiplexer 8x LED each to align with input pot
    *   Z (input) held high

  Fixed Pins
    * 8, 9, 10 - Digital pins to write multiplex addresses, (PORTB)
   
  Configurable Pins:
    * top_active - Digital pin E on the top bank (active low)
    * bot_active - Digital pin E on the bottom bank (active low)
    * top_in - Analog pin to read top bank
    * bot_in - Analog pin to read bottom bank
