  This is ArduMark V1.0 by @bockring. Don't copy this.
  But if you credit, you can edit and share your one.(Open source software)
  *From this version, ArduMark softwares are LTS(Long-Time-Support edition).

  Again, YOU HAVE TO CRADIT if you edit and share this.

  Update features
  *
  
  Status lamp(On-board LED ; Pin13) *Sometimes it doesn't works well
   Lamp ON :Processing
   Lamp OFF:Not processing(For example, cooling down time)
   Blinking:Tests are done

  How to use
  1.select serial port
  2.open serial monitor
  3.compile and flash
  4.wait for prosessings finish
  5.check the monitor, and score
  *This program is made for genuine Arduino hardwares.
   If you have compiling error, please fix by yourself or send e-mail to me.
