I am wanting to make my new LCD print what I say via serial monitor... So far I have this...

#include <LiquidCrystal.h>
int incomingByte = 0;	// for incoming serial data
String ReadString;
LiquidCrystal lcd(7, 8, 9, 10, 11, 12);

void setup() {
  Serial.begin(9600);
  lcd.begin(16, 2);
}

void loop() {

  if (Serial.available() > 0) {
      char c = Serial.read();
      ReadString += c;
      if(ReadString.indexOf('~') > 0) {
        ReadString = "";
        Serial.println("Cleared String");
        lcd.clear();
      }
    Serial.print("I received: ");
    Serial.println(ReadString);
    lcd.print(ReadString);

    }
  }
}

If you type lol it returns

I received: l
I received: lo
I received: lol

and on the LCD it prints

llolol

Does anyone know of a way to get it just to put the full word?

(sorry I am new to this type of programming!)

Hehe... thanks...
I got it to work...
And do you know how to clear the ReadString so it will erase your last word...

Clear ReadString, or clear what was printed on the LCD?

ReadString = "";

lcd.clear();

Yes.. I know that but I wish to only do this when nothing was typed for 5 seconds but i want to keep a little
lcd.print(millis()/1000) clock underneath that ...
what is the best way to do both...

(sorry still new....)

edit( I am going to do just read string so something is on the lcd at some point and always... )
