Degree Symbol Serial Monitor

Easy way to print the degree symbol on the Arduino Serial Monitor – In various applications, we sometimes need symbols that we want to display on the serial monitor.

For example, when we want to display a temperature of 10 degrees Celsius, we want to display 10 ° C.

As another example, if we want to display the resistance value of a resistance of 10 ohms, then we want it to look like 10Ω.

Arduino uses a character encoding with UTF-8 format.

UTF-8 (Universal Character Set (UCS) Transformation Format)

UTF-8 (Universal Character Set (UCS) Transformation Format) is a character encoding format developed by the Unicode Consortium that stores character data into binary data.

For example we store “hello”, the binary data is 01101000 01100101 01101100 01101100 01101111

UTF-8 is a character encoding that is widely used in web pages (html 5) and e-mails of 1 to 4 bytes in size.

Well, speaking of the Unicode Consortium, they are a non-profit company devoted to developing, maintaining and promoting software internationalization standards and data, especially the Unicode Standards, which define the representation of text in all modern software products and standards.

The Unicode Consortium is actively developing standards in the field of internationalization including defining the behavior and relationships between Unicode characters.

The consortium works closely with the W3C and with ISO and IEC – in particular with ISO / IEC / JTC 1 / SC2 / WG2, which is responsible for maintaining ISO / IEC 10646, the International Standard in sync with the Unicode Standard.

Displaying characters and symbols on the serial monitor Code Program

For writing the basic syntax of UTF-8 is: Serial.print (“UTF-8 code”).

We will try to display the following data:

  • 10 degrees centigrade
  • 90 degree angle
  • 10 ohms
  • 10 micro
  • 10 percent
  • Nokia Registered

To be like:

  • 10 ℃
  • 90 °
  • 10 Ω
  • 10 µ
  • 10%
  • Nokia®

Code Program For Show Degree Symbol Serial Monitor

The program is:

void setup() {
Serial.begin(9600);

Serial.println("10\xe2\x84\x83");
Serial.println("90\xc2\xb0");
Serial.println("10\xce\xa9");
Serial.println("10\xce\xbc");
Serial.println("10\x25");
Serial.println("Nokia\xc2\xae");
}

void loop() {
  // put your main code here, to run repeatedly:

}
