I did but it was "Kai" that came out even if the input is "boy".
I actually have a wider area of application but had to summarize it . But I am still having the same problem.
I used Arduino mega, I have equally tried with nano board and another computer but same problem.
It is supposed to return "Hi" if the choice is "boy" and return "Kai" if the choice is something else. But all returns are "Kai" irrespective of the "choice".
