02_Switch_input02 by yasusanto

This sketch is missing a short description

This program is very similar to "**e02_Switch_input01**" in principle, except that it sends a more specific human-readable messages to the serial monitor instead of "1"s and "0"s. Again, this program outputs only to [Serial Monitor](https://www.arduino.cc/en/Guide/Environment#serialmonitor) of Arduino. There is no other output (i.e. LEDs are not used). To open Serial Monitor, you need to click the magnifying glass icon at the top-right of Arduino application.  (Serial Monitor Button) A "**if...then...else**" statement (or conditional statement) determines which message is to be sent (which line of codes to be executed) depending on the state of two switches (see [if...](http://www.arduino.cc/en/Reference/If) in Arduino's reference page). For example, if both switches are pressed ("0" and "0"), Arduino sends "both ON" to the serial monitor. Please note that Arduino ports receive "0" when a switch is pressed.
