I received a parallax basic 2 stamp and accessories several years ago from a friend. I was unable to use it as program was based on windows software and RS232 connection. Can this be used for arduino programming? I also thought i saw parallax stuff being used but am very interested in the arduino software as it is open source and I am an old Linux user in my previous job.
No as the stamp used a form of the BASIC language to program in, and would not be able to work with arduino IDE C/C++ software language. It's also based on a PIC micro rather then a AVR micro that all the arduino boards use. So it was a useful learning platform in it's day, but the Arduino far surpasses it in almost every possible way. Even though you already own it, I think you would be far ahead to get an arduino and start from there.
