/*
  Example 02 - Dual Channel Current

  Reads the RMS current from both Channel A and Channel B and prints them side by side.
  Channel A is the primary CT clamp input on the Qwiic connector. Channel B is available
  via the optional pinout headers on the board.

  begin() configures default gain on both channels for you, so this sketch just reads
  the current in amps from each channel.
