SW1: Serial Monitor

The Serial Monitor is a very useful tool once the code to write moves a bit from the very basics.

We can use the Serial Monitor to print anything we want: variables’ value, values coming from a sensor, a custom debugging string and so on.

In order to open the Serial Monitor we have to connect Arduino to the PC and then to click on the magnifier icon on the right side of the Arduino IDE.
