Can anyone help me with this. I got a problem for my lcd display
when my lcd disply it shows

Security code:
when I type in my passwords, it still stick on my cursor and display 1 by 1 on the same cursor
how to make the password in 2nd line and run the character from left to right
Thanks in advances

void keypadEvent(KeypadEvent eKey){
switch (keypad.getState()){
case PRESSED:
lcd.print("Security Code:");
lcd.setCursor(0,1);
lcd.print(eKey);
switch (eKey){
case ' ': guessPassword(); break;
default:
password.append(eKey);

Sure. It prints the prompt every time you press a key. That's not right.

so what should I do, if I didn't set cursor it will clash with my security code.

Really, how could anybody answer that question without seeing your "security code"?

// this is the programming can you try run and see. actually I put the set cursor is like it stuck on that cursor when I press a digit it display and then it clear off by replacing another character 



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


SoftwareSerial mySerial(2, 3);
LiquidCrystal lcd(12,11,5,4,3,2);
Password password = Password( "1402" );
 const byte ROWS = 4; // Four rows
 const byte COLS = 3; // Three columns

 
 // Define the Keymap
 char keys[ROWS][COLS] = {
   {'1','2','3',},
   {'4','5','6',},
   {'7','8','9',},
   {'*','0',' ',}
 };
// Connect keypad ROW0, ROW1, ROW2 and ROW3 to these Arduino pins.
 byte rowPins[ROWS] = {25, 24, 23, 22}; //connect to the row pinouts of the keypad
 byte colPins[COLS] = {28, 27, 26}; //connect to the column pinouts of the keypad
 const int buttonPin = 7;
 int buttonState = 0;

 // Create the Keypad
 Keypad keypad = Keypad( makeKeymap(keys), rowPins, colPins, ROWS, COLS );

 #define ledPin 13

 void setup(){
 pinMode(buttonPin, INPUT);
 lcd.begin(16, 2);
 digitalWrite(ledPin, LOW); // sets the LED on
 Serial.begin(9600);
 keypad.addEventListener(keypadEvent); //add an event listener for this keypad
 keypad.setDebounceTime(250);
 }

 void loop(){
 keypad.getKey();
 buttonState = digitalRead(buttonPin);
 if (buttonState == HIGH) {
 lcd.clear();
 
 }
 }

 //take care of some special events

 void keypadEvent(KeypadEvent eKey){
 switch (keypad.getState()){
 case PRESSED:
 lcd.print("Security Code:");
 lcd.setCursor(0,1);
 lcd.print(eKey);
 switch (eKey){
 case ' ': guessPassword(); break;
 default:
 password.append(eKey);
 }
 }}

 void guessPassword(){
 if (password.evaluate()){
 digitalWrite(ledPin,HIGH); //activates garaged door relay
 delay(500);
 digitalWrite(ledPin,LOW); //turns off door relay after .5 sec
 lcd.print("VALID PASSWORD "); //
 password.reset(); //resets password after correct entry
 delay(600);
 lcd.print("Welcome");
 delay(2000);
 lcd.clear();
 }


 else{
 digitalWrite(ledPin,LOW);
 lcd.print("INVALID PASSWORD ");
 password.reset(); //resets password after INCORRECT entry
 delay(600);
 lcd.clear();
 }
 }

Moderator edit: CODE TAGS, DAMMIT!

You have to separate the action of printing a prompt and collecting the input. Two different tasks.

ok problem solve, I forgot I put at loop, no wonder it is not working. instead I put set cursor on the void setup

thanks for helping guys
