The received text from the Arduino board will show up in the serial monitor and you can also send text messages over UART using this graphical interface. You just need to set the baud rate to the same value you’re using in your Arduino project and you’re good to go. The Arduino IDE is equipped with a graphical interface tool called “Serial Monitor” that you can use to communicate with your Arduino board over the serial port (UART). Start Programming in Python: 9 Ways to Print Hello World #python #programming So it basically, sends whatever text you want with a newline termination special character. print ( ) function with only one difference which is following the printed text with a carriage return character (ASCII 13, or ‘\r’) and a newline character (ASCII 10, or ‘\n’). print ( ) returns the number of bytes written, though reading that number is optional. For floating point numbers, this parameter specifies the number of decimal places to use. print ( ) function does not append a newline character at the end. It allows you to display information, debug messages, or sensor readings in a readable format.
It accepts various data types such as integers, floating-point numbers, strings, and characters. print ( ) function is used to send data as human-readable text over the UART interface.

We’ll also discuss how to use Arduino’s Serial Monitor For Debugging your Arduino projects. We’ll discuss how the Arduino Serial.print() & Serial.println() functions work and how to use them to print various data types to the serial port. In this tutorial, you’ll learn how to use the Arduino Serial.print() & Serial.println() Functions.
