Controlling Direction and Speed Controlling the Direction and Speed

The pairs of DC motors on the left side are wired to the dedicated PWM channels. This means that *ESP32-C3 Breadboard DevBoard* can control rotation speed and direction of DC motors in pairs only (i.e. left and right side). The pairs of DC motors on the left side are wired to the dedicated PWM channels. This means that *ESP32-C3 Breadboard DevBoard* 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.
