How do you see the Arduino Serial.print() output?

I realised that when I was trying to learn how to use the Arduino IDE, I could not readily find the output console to "see" the output from "Serial.print()" or "Serial.println()".

The following is a newbie guide:

1. Open the IDE -> Tools -> Serial Monitor.
2. Change the "Baud rate" setting to the same number in the code. E.g. "Serial.begin(115200);" means the baud rate is 115200.
3. After you switch to the correct baud rate, which is like tuning in to a radio channel on radio, you should see the output of the print command.

Good luck figuring this out!
