A higher duty cycle increases the motor speed, and a lower duty cycle decreases the motor speed. This allows for fine-grained speed control
without needing analog voltage regulators.
A pair of PWM channels are required for defining rotation speed and direction of the DC motors on each side.
A pair of PWM channels are used per DC motor for defining their rotation speed and direction on each side.
In particular, **GPIO6** and **GPIO5** provide PWM to the left- and right- side DC motors to rotate in a **clockwise** direction.
Similarly, **GPIO4** and **GPIO7** provide PWM to the left- and right- side DC motors to rotate in a **counter-clockwise** direction.
Changing PWM on each channel determines the speed and direction of the RC car.
