M2 P29 21
PWMA P25 26
M3 P22 6
M4 P23 13
PWMB P26 12

M1 and M2 are connected to the right motor, while M3 and M4 are connected to the left motor. PWMA and PWMB are output enable pins, active high enable. When they are driven to High level, the PWM pulse will be outputted from M1, M2, M3 and M4, so as to control the speed of the robot.

Control work

1 0 1 0 When the motors rotate forwards, the robot goes straight
0 1 0 1 When the motors rotate backwards, the robot draws back
0 0 1 0 When the right motor stops and left motor rotates forwards, the robot turns right
1 0 0 0 When the left motor stops and right motor rotates forwards, the robot turns left
0 0 0 0 When the motors stop, the robot stops
