Hello, I have a question. How do I clear whatever is printed to the serial port?
Not sure what you mean here.
Depends entirely on what device is at the other end of the serial connection accepting and displaying the characters.
The built-in "Serial Monitor" appears not to have any such capability.
Oh. Well nevermind then, I can't really right programs beside windows batch, and I'm not good at that.
How do I make a new line?
println
or Serial.print("\n");
\n is the code for newline.
Serial.print("hello\n");
will produce exactly the same output as
Serial.println("hello");
sometimes it's easier to use the newline character as for example if you want to print several lines with
one statement like:
Serial.print("Hello\nMy name is Henry\nWhat is yours?\n>");
which will produce the following output:
Hello
My name is Henry
What is yours?
If you want it to work the same on every computer, use "\r\n" instead of "\n": then it'll display properly on windows, linux, and mac.
