Pair-of-motors control interface.
Often our robots use two motors, one on either side, which should be controlled together as one. This class makes this simple by allowing the coder to treat the pair as a single motor.
The two motors can be connected to any of the output ports. When creating an instance of this class, simply specify which two output ports are involved.
The normal Motor methods speed(), direction(), forward(), reverse(), brake(), and off() still apply.
This class adds two new types of control:
