On of the new command types in Gobetwino 0.6 (coming soon) will allow Arduino to send the command line parameters to a started program. I have this running by now, and have been experimenting with running VB scripts with the command line coming from Arduino. This opens up a whole lot of new possibilities.
VB script is very powerful, and just by Googeling a little i have found VB scripts to do almost anything i can imagine.
I have made a few short experiments, and found that things like browsing to a website with querystring parametres coming from Arduino, like http://www.site.com?name=value where value is something coming from Arduino, is a piece of cake. Another thing i have successfully tested today is inserting data into a (SQL server) database from a VB script started from Gobetwino. The Windows Script Host (WSH) that executes the scripts also supports Jscript, VB’s, JAVA cousin, so if you are more JAVA than VB inclined, no problem.
So the bottom line of todays experiments is that if it can be done in VB script og Jscript, it can be done with Gobetwino, and therefore also from Arduino.
