A way to generate a tiny bit more useful random numbers on Arduino

randint.ino

long rand(int min, int max) {
  long result;
  for (int i = 0; i < analogRead(A0); i++)
  {
    randomSeed(analogRead(A0));
    result = random(min, max);
  }
  return result;
}

long rand(int max) {
  return rand(0, max);
}
