MWC Battery Voltage Monitoring kit

Use this to get the battery voltage to your mega/mwc boads.

Inline Resistors with JST plug.

Buzzer with wire.

Now change the pin used for the buzzer toggle in def.h. This can be done several ways but this works. Add the three lines in bold and then comment out the other three lines
