With the knowledge I have all I get from the Arduino com port monitor is a scrolling mass of numbers.
Perhaps because that is all you are sending it. You can do better. Suppose you are using a ping sensor to get a distance. Of course, the simple thing to do is:
Serial.println(distance);
and a number will appear in the Serial Monitor. On the other hand, you can do:
Serial.print("distance = ");
Serial.println(distance);
and the number will appear, after some descriptive text that describes what the value is.
That hardly seems like rocket science, or a reason for a new Serial Monitor application.
