The F (for Free version) after the version number indicates the Simulator is identical to the Pro Version but . The Free version has been provided as demo version to allow the Simulator for Arduino program to be evaluated prior to purchase. It is anticipated that after a month of use, it will be more economically viable to purchase the Pro Version than continue to run the Free Version.


Limitiations of the Free version are:

  • a Code limit of 150 lines which will be displayed on the Delay Timer screen
  • an incrementing delay timer (from 30 seconds) window any time a new sketch is loaded or edited
  • A trial period of 30 days or 10 sketches with no timer after an unlock process
  • An initial trial period of 30 minutes (no unlock required)
