Ver1.09 support Adrian&Fred Flux Capacitor unit.

・I2C DAC Breakout - MCP4725

If use Fred’s flux then need Arduino sketch edit.
Please change word "FluxUnit = 0" to "FluxUnit = 1" .
--------------------------------------------------------------------------------------------
int FluxUnit = 0; // Fred Wendland Flux Capacitor board use change 0 to 1.
--------------------------------------------------------------------------------------------
Please
Please check your MCP4725 Address setting.
