Oliver naprogramoval prvú verziu rozpoznávania lopty:

int je_lopta(uint8_t r, uint8_t g, uint8_t b)
{

  float h, s, v, max, min;
  h = 0;
 
   if (r < b){
    if(r < g){
      min = r;
    }
    else{
      min = g;
    }
  }
  else{
    if (b < g){
      min = b;
    }
    else{
      min = g;
    }
  }



  if (r > b){
    if(r > g){
      max = r;
      if (max!= min){
        h = 60*((g-b)/(max-min));
      }
    }
    else{
      max = g;
      if (max!= min){
        h = 60*(2+(b-r)/(max-min));
      }
    }
  }
  else{
    if (b > g){
      max = b;
      if (max!= min){
        h = 60*(4+(r-g)/(max - min));
      } 
    }
    else{
      max = g;
      if (max!= min){
        h = 60*(2+(b-r)/(max - min));
      }
    }
  }
 
  v = max;

  s = (max-min)/max;
  if (h < 0){
    h = h + 360;
  }
  if (h < 28 && h > 8 && s > 0.5 && v > 100){
    return 1;
  }
  return 0;
}
