How to Clear Serial Monitor in Arduino IDE
The serial monitor is a useful tool for debugging and testing your Arduino projects. It allows you to send and receive data between your computer and your Arduino board via a USB cable. However, sometimes you may want to clear the serial monitor screen to remove the previous messages and start fresh. In this article, we will show you how to clear the serial monitor in Arduino IDE using different methods.
Clear Serial Monitor Arduino
Method 1: Close and Reopen the Serial Monitor
The simplest way to clear the serial monitor is to close it and reopen it again. This will also restart the Arduino board, so any code that is running on it will be reset. To do this, you can either click on the x button on the top right corner of the serial monitor window, or use the keyboard shortcut Ctrl+Shift+M. Then, you can reopen the serial monitor by clicking on the magnifying glass icon on the top right corner of the Arduino IDE, or using the same keyboard shortcut.
Method 2: Use Another Serial Terminal Program
Another option is to use a different serial terminal program instead of the built-in serial monitor in Arduino IDE. There are many free and open-source serial terminal programs available, such as [PuTTY], [RealTerm], [Termite], etc. These programs usually have more features and options than the serial monitor, such as logging, filtering, formatting, etc. They also support various escape sequences that can be used to clear the screen, move the cursor, change the color, etc.
For example, to clear the screen using PuTTY, you can send the following escape sequence from your Arduino code:
Serial.print("\033[2J"); // \033 is the escape character
This will erase all the characters on the screen and move the cursor to the top left corner. You can also use other escape sequences to perform different actions, such as:
\033[H: move the cursor to the top left corner
\033[K: erase from the cursor to the end of the line
\033[m: reset all attributes (color, brightness, etc.)
\033[30m: set foreground color to black
\033[31m: set foreground color to red
\033[32m: set foreground color to green
\033[33m: set foreground color to yellow
\033[34m: set foreground color to blue
\033[35m: set foreground color to magenta
\033[36m: set foreground color to cyan
\033[37m: set foreground color to white
\033[40m: set background color to black
\033[41m: set background color to red
\033[42m: set background color to green
\033[43m: set background color to yellow
\033[44m: set background color to blue
\033[45m: set background color to magenta
\033[46m: set background color to cyan
\033[47m: set background color to white
To use another serial terminal program, you need to make sure that it is configured with the same settings as your Arduino board, such as baud rate, data bits, parity, stop bits, etc. You also need to close the serial monitor in Arduino IDE before opening another program, otherwise they will conflict with each other.
Method 3: Print Blank Lines or Separator Characters
A third method is to print blank lines or separator characters from your Arduino code to simulate clearing the screen. This is not a real clear screen command, but it can achieve a similar effect by pushing the previous messages out of view. For example, you can use a loop to print a certain number of newlines (\n) or spaces ( ):
for (int i = 0; i < 50; i++) Serial.println(); // print a newline // or Serial.print(" "); // print a space
Alternatively, you can print a string of characters to indicate the end of a section, such as:
Serial.println("========================");
This method is not very elegant, and it may not work well if you have a lot of data to display or if you want to clear the screen frequently. It also depends on the size and resolution of your serial monitor window, which may vary on different devices.
