In particular, <strong>GPIO6</strong> and <strong>GPIO5</strong> provide PWM to the left- and right- side DC motors to rotate in a <strong>clockwise</strong> direction.
Similarly, <strong>GPIO4</strong> and <strong>GPIO7</strong> provide PWM to the left- and right- side DC motors to rotate in a <strong>counter-clockwise</strong> direction.
Changing PWM on each channel determines the speed and direction of the RC car.</p>
