![]() ![]() Here is the full code listing for this example. Hello World ! !” over the serial port and we’ll view it on the serial monitor. This function performs the same as the Serial.print () function with the difference that this function goes to the next line after printing the variable value. This is a simple Arduino example code to print the message “ If you want to print variables on different lines, you can do that easily using the Serial.println () function in Arduino. So, let’s get started with the Arduino serial print code examples! Serial Print Hex & Binary format variables.Serial Print string text & numeric variables.println ( ) functions using the Arduino Serial Monitor to achieve the following tasks: In the next sections, we’ll do some practical examples to test the And it’s really helpful for debugging your Arduino projects by sending the value of variables and flags to check them in real time using the serial monitor. The Arduino Serial Monitor saves you the time and effort to use external serial terminals on your PC. 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). print ( ) function that we’ve discussed before. So it basically, sends whatever text you want with a newline termination special character.Įverything else is exactly the same as the 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. ![]()
