成员功能

The battery class includes the following member functions:

• voltage — Returns the battery voltage.

• current — Returns the battery current draw.

• capacity — Returns the remaining battery capacity.

• temperature — Returns the battery temperature.

Before calling any battery member functions, a brain instance must be created, as shown below:

// Create the V5 Brain
brain Brain = brain();
