Using L298 Motor driver
-----------------------
the wiring between the L298 motor driver and arduino board is defined in motor_driver.h in the firmware as follow:
#define RIGHT_MOTOR_BACKWARD 5
#define LEFT_MOTOR_BACKWARD 6
#define RIGHT_MOTOR_FORWARD 9
#define LEFT_MOTOR_FORWARD 10
#define RIGHT_MOTOR_ENABLE 12
#define LEFT_MOTOR_ENABLE 13
wire them this way or change them if you want, and make sure that the L298 motor driver is defined then compile and upload the firmware.
