  while (m = 1 && m > 300 && m <  700)
  {
    i.mode1();
  }
  Serial.println(m);
  delay(1000);
}

after run the serial monitor print out as 0

Oops

do you mean

while (m == 1 && x > 300 && x <  700)

?

you again!
i'm such an idiot

Be proud of yourself!
You make beginner errors (that experienced programmers may still make).
But you are trying. That is what matters!

You seem to have started a second topic on the same subject

Why ?

why i cant

Asking the same question multiple times wastes the time of those offering help. Did you not like the replies that you got here ?
