 The Motor Board can be used to control two 12V DC motors. Your kit contains two of these boards to allow you to control up to four motors. These can be used for moving your robot, although don't feel you are limited to using them for this purpose.
 
-The speed and direction of the two outputs are controlled independently through the USB connection. The board also needs power delivered from a 12V port on the Power Board in order to drive the motors. 
+The speed and direction of the two outputs are controlled independently through the USB connection. The board also needs power delivered from a 12V port on the Power Board in order to drive the motors.
 
 The motor board uses [pulse-width modulation][wiki-pwm] (PWM) to control the
 amount of power that is sent to the motors.
