how do I buffer serial to receive words instead of single characters?

hi everyone,

i'm having trouble code.. here's background: i've linked bluetooth phone, , want able send messages arduino. however, when type send word, sends out characters individually. i'm trying write code buffer characters , print when type period. here's code:

any tips? btw, i'm using 46 because think equals "." yeah? =)

code: [select]


const int sens_pin = a0;
const int led_pin = 13;

int sensorvalue = 0;
int x = 0;
int words[100];

boolean toggle = true;

void setup()
{
    serial.begin(9600);
    pinmode(13, output);
    pinmode(2, output);
    pinmode(3, output);
    digitalwrite(2, low);
    digitalwrite(3, high);
}

void loop()
{ 
  inputbuffer();
   
 
 
 
}

void inputbuffer()
{
  if (serial.available())
    {
        words[x] = serial.read();
           
       
        if(words[x] = 46)
        {
          int i;
          serial.print("got: ");
          (i = 0; < x; i++)
          {
          serial.print(words[i]);
          }
          serial.println("");
        }
       
        serial.print(words[x]);
        digitalwrite(led_pin, toggle); // toggle led
        toggle = !toggle; 
       
        x = x+1;
    }
 
}

btw, i'm using 46 because think equals "."

then, why not use '.'?

code: [select]

int words[100];
one not read ints serial port. 1 not read words serial port.

code: [select]

void loop()
{ 
  inputbuffer();
   
 
 
 
}
could maybe add few more useless blank lines?

code: [select]

        if(words[x] = 46)
assigning 46 words

• succeed, test true. ==?
  
  the words array should have better name. type should char. after each character added, null needs added after (but don't increment index again).
  
  
  code: [select]
            (i = 0; < x; i++)
          {
          serial.print(words[i]);
          }
  if null terminated array, , right size/type, wouldn't need loop print it.
  
  at point, might idea reset 0.
