Controlling the DC motors

The motors cannot be driven by the Arduino PWM outputs directly but they must pass through a motor driver boosting the signal power In our case an L298N bridge is used, which is well described on this page.

This table shows how the driver module is connected to the Arduino Uno:

The following pins on the Arduino Uno are PWM pins:
