I have started with a project to control some functions in my Trailer.
Now everything works fine.
I wonder how to add "°" and "%" ?
SIM900.println("AT + CMGS = \"+46123456789\""); // recipient's mobile number, in international format
delay(100);
SIM900.println("Indoor temp:"); // message to send
SIM900.println(t);
SIM900.println("Indoor humidity:");
SIM900.println(h);
I like to send:
Indoor temp: 21.00°
Indoor humidity: 44.00%
Any help will be greatly appreciated !
