Arduino new line

A simple but important topic!

In Arduino, when you want to print a new line, you can use the println() function. This function prints the output followed by a newline character (\n).

Here's an example:

Serial.println("Hello, world!");

This will print "Hello, world!" followed by a newline character, so the output will be:

Hello, world!

If you want to print a new line without printing a newline character, you can use the print() function instead:

Serial.print("Hello, world!");
Serial.println();

This will print "Hello, world!" and then print a newline character, so the output will be:

Hello, world!

Note that println() is a shortcut for print() followed by println(), so you can use either one depending on your needs.

Also, if you're using a serial monitor like the Arduino Serial Monitor, you can use the "Newline" option to automatically add a newline character at the end of each line.
