Here is a program with a text LCD that shows the temperature. We already formatted the thermometers output to get a human readable string on the LCD like “Temp: 14.3C”.
format-number node transforms the number value to a string with a desired precision.
concat node concatenates a three parts of the string that we want to see on the display.
To show non-ASCII characters you should specify its hexadecimal character code in the special “\x” notation. Codes differ on various LCD models. For example, if you have an MT-16S2H, the degree character is “\x99”. Check out character tables for your model in its datasheet.
Let’s improve the thermometer to show the degree character on the LCD.
