  This is ArduMark V1.1 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).

  This program was edited and remixed by XXXX(Your name).
  Remix source:https://github.com/bockring/ArduMark.git
  "
  Again, YOU HAVE TO CRADIT if you edit and share this.

  Update features
  *Add some calculation features(Remainder of division/Abs)
  *Add the calculation times of square root

  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.(Especialy for Arduino UNO R3)
   If you have compiling error, please fix by yourself or send e-mail to me.
