Arduino Float to String (That actually works) - Protoneer

Displaying FLOAT variables in Arduino. It seems that the Arduino software doesn't have much support for displaying float variables, certainly the sprintf() function doesn't work. However there is a useful c function called dtostrf() which will convert a float to a char array so it can then be printed easily.
