Oct 1, 2019 · Just start a new line, you don't need any special syntax. Statements are terminated by semicolons, not by line endings. Pieter

Probably you should use "\r\n" instead of "\n" at the end of lines. More detailed: "\n" is character with code 0x0A called "new line", while "\r" is 0x0D - "carriage return". Different terminals understand these characters in different ways: there is DOS-like way, when "\n" just places carriage down one line, not changing horisontal position.

Jul 23, 2019 · Arduino serial port can send new line, line feed LF and carriage return CR character by its ASCII codes. Both write and print function supports the r and n special character.

Apr 23, 2025 · Prints data to the serial port as human-readable ASCII text followed by a carriage return character (ASCII 13, or '\r') and a newline character (ASCII 10, or '\n'). This command takes the same forms as Serial.print (). : serial port object. See the list of available serial ports for each board on the Serial main page. : the value to print.

Use escape characters to include new-line/line-feed in a serial message. Command strings can be used in any property that sends messages to connected devices. These properties start with the word On.

You can use print() (as opposed to println() which adds a newline). Serial.print("Cat "); Serial.print("Dog "); Serial.print(48); Serial.print(" "); Serial.print(x); Serial.println(); If that's too much code, you can use C's printf approach (as already mentioned elsewhere). printf("Cat Dog %d %d\n", 48, x); but you'll also need something like
