Hi i new with arduino, i like basic stamp from parallax, but now is to limited.
i have a problem with multiples input from a key pad, works the first input, but in the next
don do anything, here my code :

I really need some help with this

#include <Keypad.h>
#include <SoftwareSerial.h>

const byte rows = 4;
const byte cols = 4;

int count_grupo_a = 0;
int count_grupo_b = 0;
int count_grupo_c = 0;
int count_grupo_d = 0;

char keys[rows][cols] = {
  {'1','2','3','A'},
  {'4','5','6','B'},
  {'7','8','9','C'},
  {'*','0','#','D'}
};

byte rowPins[rows] = {2, 3, 4, 5};
byte colPins[cols] = {6, 7, 8, 9};

Keypad keypad = Keypad( makeKeymap(keys), rowPins, colPins, rows, cols );

void setup()
{

  Serial.begin(9600);
  delay(500);
  //Keypad.addEventListener(keypadEvent);  // Add an event listener.
  //keypad.setHoldTime(500);               // Default is 1000mS
  //keypad.setDebounceTime(250);           // Default is 50mS
  clearLCD();
  selectLineOne();
  Serial.print(" Score Dominoes ");
  selectLineTwo();
  Serial.print("Group:");

}

void loop()
{
  char key = keypad.getKey(); -------> Work
 
  if (key != NO_KEY){
    if (key == 'A') {
      clearLCD();
      group_a();
      }
    }
   
  }


void group_a()
{
          Serial.println("GRUPO A");
          selectLineTwo();
          Serial.println("Valor :");
          int valor_a = keypad.getKeys(); ---------> nothing
          if (valor_a != NO_KEY){
          count_grupo_a = valor_a + count_grupo_a;
          Serial.println(count_grupo_a);
          delay(2000);
          setup();
        }
 
}

void selectLineOne(){  //puts the cursor at line 0 char 0.
  Serial.write(0xFE);   //command flag
  Serial.write(128);    //position
  delay(10);
}
void selectLineTwo(){  //puts the cursor at line 0 char 0.
  Serial.write(0xFE);   //command flag
  Serial.write(192);    //position
  delay(10);
}
void goTo(int position) { //position = line 1: 0-15, line 2: 16-31, 31+ defaults back to 0
  if (position<16){
    Serial.write(0xFE);   //command flag
    Serial.write((position+128));    //position
  }
  else if (position<32){
    Serial.write(0xFE);   //command flag
    Serial.write((position+48+128));    //position
  }
  else {
    goTo(0);
  }
  delay(10);
}

void clearLCD(){
  Serial.write(0xFE);   //command flag
  Serial.write(0x01);   //clear command.
  delay(10);
}
void serCommand(){   //a general function to call the command flag for issuing all other commands
  Serial.write(0xFE);
}

Please edit your post to place your code between code tags.

If you'd read the stickies at the top of the forum you'd know to do that already.

This should have everything you need. http://arduino.cc/forum/index.php/topic,140459.0.html

Code:

Serial.begin(9600);
  delay(500);
  //Keypad.addEventListener(keypadEvent);  // Add an event listener.
  //keypad.setHoldTime(500);               // Default is 1000mS
  //keypad.setDebounceTime(250);           // Default is 50mS
  clearLCD();
  selectLineOne();
  Serial.print(" Score Dominoes ");
  selectLineTwo();
  Serial.print("Group:");

Any reason you commented out the "Debounce" routine.  The problem you are describing is a "bounce" issue.
