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.
