Kind of I noob question I guess, but I don’t get it to work. Really 've been searching all evening.
I’ve got a part of a LCD library (shift register) here:
void ByVacLCD::send3(int test) {;
Wire.beginTransmission(_adr);
Wire.send(0x02);
Wire.send(test);
Wire.endTransmission();
delayMicroseconds(45);
}
But what I want is the variable between quotations:
Wire.send("test");
How? :-[ :-[
/EDIT:
Can’t believe it I actually found it 
void ByVacLCD::send3(int test) {
char buf[5];
itoa(test, buf, 10);
Wire.beginTransmission(_adr);
Wire.send(0x02);
Wire.send(buf);
Wire.endTransmission();
delayMicroseconds(45);
}
Hope maybe somebody can learn from it
