Random number generator

long randomnum;  //creates the variable randomnum 
int floatingpin = 0;  //creates the variable floatingpin
const int emptypin = A1;  //put an unused analog pin in here
void setup() {
  Serial.begin(9600);  //initialises the serial port
  randomSeed(23); //put any number in here
  pinMode(emptypin, INPUT);  //sets emptypin as an input
}
void loop() {
  floatingpin = analogRead(emptypin);  //sets floating pin to the value of the empty pin
  randomnum = random(2,176);  //put a low number and a high number in here, they are the variables that set the parameters of the randomness.
  Serial.println(randomnum);  //prints out the number
  randomSeed(randomnum/(randomnum*(randomnum*floatingpin)));  //sets the seed to a comletely random number
  delay(randomnum);  //waits for how long the random number is
