Instead of:

switch (loopCount) {
          case 10: Serial.println("10"); break;
          case 9: Serial.println("9"); break;
          case 8: Serial.println("8"); break;
          case 7: Serial.println("7"); break;
          case 6: Serial.println("6"); break;
          case 5: Serial.println("5"); break;
          case 4: Serial.println("4"); break;
          case 3: Serial.println("3"); break;
          case 2: Serial.println("2"); break;
          case 1: Serial.println("1"); break;
          case 0: Serial.println("0"); break;
          }

Why not just:Serial.println(loopCount);???
