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).
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.
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.
