Potentiometer regulating motor...noot easy

[gcjr]

@francescoranchi

'm trying to add a second potentiometer that will let me regulate the speed at which the motor is turning

@francescoranchi

  int pot_value = analogRead(A0);
  
   int motor_speed = map(duration, 0, 9000, 255, 0);

the max motor speed, 255, is "mapped" to 9000. what about using the pot value to set the value corresponding to 9000?
