/30/2013The char type holds a single byte value. Usually used for reading/writing single characters. The above converst to a string, although I'm pretty sure there's no such thing as a string, per-se, in C/C++, just an array of char or pointer to char. Converting to a C++ String object is another story.

Arduino how to convert int to char array - King Au's web page

Data Types in Arduino; char (8 bit) - signed number from -128 to 127. The compiler will attempt to interpret this data type as a character in some circumstances, which may yield unexpected results int (16 bit) - signed number from -32768 to 32767. This is most commonly what you see used for general purpose variables in Arduino example
