This means that <em>ESP32-C3 Breadboard DevBoard</em> can control rotation speed and direction of DC motors in pairs only (i.e. left and right side).
Consequently, only four PWM channels are sufficient for controlling the direction of the RC car. Consequently, only four PWM channels are sufficient for controlling the direction of the RC car.
Based on this constraint, the RC car can only move front, back, and turn/rotate left and right. Any other movements are not possible (i.e. diagonal or sideways).</p> Based on this constraint, the RC car can only move front, back, and turn/rotate left and right.
