Let me start by explaining that I am an absolute beginner!
I am playing with a DS18B20 and displaying the temp in the serial monitor. That is working, but I was just trying to show the temp with a degree symbol like... °C. I can't seem to figure out how to send the degree character (248). Any tips?
Thanks for the help. I'm also workign on figuring out how to display the temp in °F. I'm new to electronis and C, so this is all making me scratch my head a lot.
