Serial.print() vs Serial.println()?

What are differences between Serial.print() and Serial.println()?

Answer

Both Serial.print() and Serial.println() prints number, string to Serial Monitor. However, Serial.println() prints more two characters prints Carriage Return '\r' and new line '\n' characters at the end.

What is Carriage Return '\r' and New Line '\n' characters ⇒ Simply, When you press Enter key on your keyboard, the Carriage Return '\r' and New Line '\n' characters is included in your text editor. It means after using Serial.println(), Next numbers or String will be displayed in a new line.

Let's see two examples to know the difference:

Example with Serial.print()

void setup() { Serial.begin(9600); Serial.print("Arduino"); Serial.print("Get"); Serial.print("Started"); Serial.print(".com"); } void loop() { }

The result on Serial Monitor

Example with Serial.println()

void setup() { Serial.begin(9600); Serial.println("Arduino"); Serial.println("Get"); Serial.println("Started"); Serial.println(".com"); } void loop() { }

※ NOTE THAT:

The below code:

Serial.print("Arduino\r\n");

Is equivalent to

Serial.println("Arduino");
