@@ -24,8 +24,8 @@ Consequently, only four PWM channels are required for controlling the direction
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.
