horace:
have a look at the arduino random documentation

Thanks for the quick reply,

I've already saw that, but it's with numbers, I don't know how to do it with text,
Here's the code I've tried out, this one is just to print in Serial Monitor, then I will do with LCD..

long randNumber;



void setup() {

 Serial.begin(9600);
   randomSeed("A","B");
}

void loop() {
   randNumber = random();
  Serial.println(randNumber);

  delay(50);
  

}

I get this error :

exit status 1
too many arguments to function 'void randomSeed(long unsigned int)'

Thanks..
