The second is to give the engine power to stop fast. ![]() The first one is to cut off the power to the motors and make it stop freely. There are two ways to stop the motors as shown in the table. These situations are shown in the table below. “ENA” controls “MotorA” while “ENB” controls “MotorB”. Thus, we can adjust the speed of the motors by sending a PWM signal to these pins. The “ENA” and “ENB” pins on the module enable us to turn the output power on and off.
