Consequently, only four PWM channels are required for controlling the direction of the RC car.
Based on this constraint, the RC car can only move front, back, and rotate left and right. Any other movements are not possible (i.e. diagonal).</p>
<p>A pair of PWM channels are required for defining rotation speed and direction of the DC motors 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.</p>
