Hi Serial.print(int(temp_air)); Serial.print(" °C. Humidity: "); Give me Temperature: 17 Â°C... How can i get it ? i tried Serial.println(&deg); or &#176 thanks

It's a non-ASCII character so you can't print it as a normal character. You can add a custom character / image but that depends on the LCD (library) used.

septillion: It's a non-ASCII character so you can't print it as a normal character. You can add a custom character / image but that depends on the LCD (library) used. I believe he's using Serial.... try like this... Serial.print(char(176));

You're right :o Just answered some threads about LCD's so in my head I assumed this was a LCD as well. For a single char it's easier to use Serial.write(176); No need for a case then. Inline you can do Serial.print(int(temp_air)); Serial.print(" \xB0""C. Humidity: "); Yes, the "" is a bit ug…

The HD44780 lcd controller has a built in character set. See table 4 of the data sheet [image] lcd.print(223) or lcd.print(0xDF) will print a degree symbol.

It is an ASCII character. But the Arduino IDE is Unicode. You can type a º in your code and upload it to the Arduino - it will work perfectly. If you save that file, then it gets converted to Unicode, which uses two bytes to represent that character. Reloading it will show the º in the editor but it…

MorganS: The best way to do it is to give the degree symbol a name by creating a character constant using the char(167) operator. (Or is it a cast? I can never get the terminology right.) Did you mean 176?

Serial.print(char(176)); works nicely... thanks very much ... nuff answer in few time this forum is great... @Catledog : thanks for complete explanation bro i will for sure keep this array for my lcd... first i try my project direct in serial to get hand on hardware and coding.... and also my lcd …

But How did you find 223? or xB0 ? i see only 1 and 0 in the array .. did you make a translation from binary to hexa? The table is presenting all the 8 bit binary values for the characters in the controller memory. The high four bits are given across the top, and the low four bits are given down …

MorganS: It is an ASCII character. No it's not :wink: It's an extended ASCII character. 0:-) But thanks for the explanation! MorganS: (Or is it a cast? I can never get the terminology right.) I would say it's a cast. A char holding 176 is indeed a way but that would make it harder to store…

thanks for precision.. u a master man... read the 1 and 0 ? i'm impress.. Bless. I put it as resolved and change the title a little ...
