Tom, I think the OP wants to store the value of the char variable c into the first element of two_character_string, not the letter 'c'.// otherwise, just print all normal characters
two_character_string[0] = c;
two_character_string[1] = 0; // this can be put in setup()
LCDString(two_character_string);
Ahh right, in which case you just need to remove the ' '
char two_character_string[2] = {c,0};
