increase the frequency over 300 hz

hey guys,

my name raunak , have write program can change frequency. no matter how ever changes make frequency not going on 300hz.

here program.

string instring = "";    // string hold input
const int ledpin = 9;
const int ininder = 5;
void setup() {
  // open serial communications , wait port open:
  serial.begin(9600);
  pinmode(ledpin, output);
  pinmode(ininder, input);
  while (!serial) {
    ; // wait serial port connect. needed native usb port only
  }
}
void loop() {
  if (serial.available() > 0) {
    int inchar = serial.read();
   
    if (isdigit(inchar)) {
      instring += (char)inchar;
    }
      if (inchar == '\n') {
      serial.println(instring.toint());
    // int = analogread(ininder);
    // serial.println(i);
      int = 0;
      while(i==0){
      digitalwrite(ledpin, high);
     delay(5000/instring.toint());
      delay(1);
      serial.println(5000/instring.toint());
      digitalwrite(ledpin, low);
      delay(5000/instring.toint());
      delay(1);
      analogread(i);
      }
      instring = ""
      ;
    }}}

for our sakes, including yours, please auto format code before posting , use code tags when do.  done looks this

code: [select]


string instring = "";    // string hold input
const int ledpin = 9;
const int ininder = 5;
void setup()
{
  // open serial communications , wait port open:
  serial.begin(9600);
  pinmode(ledpin, output);
  pinmode(ininder, input);
  while (!serial)
  {
    ; // wait serial port connect. needed native usb port only
  }
}
void loop()
{
  if (serial.available() > 0)
  {
    int inchar = serial.read();

    if (isdigit(inchar))
    {
      instring += (char)inchar;
    }
    if (inchar == '\n')
    {
      serial.println(instring.toint());
      // int = analogread(ininder);
      // serial.println(i);
      int = 0;
      while (i == 0)
      {
        digitalwrite(ledpin, high);
        delay(5000 / instring.toint());
        delay(1);
        serial.println(5000 / instring.toint());
        digitalwrite(ledpin, low);
        delay(5000 / instring.toint());
        delay(1);
        analogread(i);
      }
      instring = ""
                 ;
    }
  }
}

it not answer question may make problem easier find.
