GPIO5 and 6 on Raspberry Pi controls the rotate directions of Motor A and B. Two pins of both
channels are combined using a transistor, for less GPIO using. So, motors only have clockwise
and counter-clockwise controls, with 0/1. And stops uses PWM value 0
PWM 10, 11 on PCA9685 controls the speed of Motor A and B. Set Value to 0 to stop the
motor.
If you're using other DC motors with different ports, connect them based on the following
