 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.

 Changing PWM on each channel determines the speed and direction of the RC car.
