Have a good time…sorry for typos

I agree the phidget documentation is sorely lacking, if you have the chance to look into arduino hardware instead I would recommend it – the supporting community and documentation well and truly make up for the learning curve. Phidgets aren’t impossible to get working in processing, the java library does exist and it should help point you in the right direction, just go to the java section of the phidgets website.

I had a look at your code, it seems like the copy+paste between processing and wordpress isn’t the cleanest method – some commented lines get wrapped and smart quotes are another problem. I cleaned that up a little bit, it was just a simple matter of checking each of the open and close braces { and }. Give this a try (and don’t forget to download the phidget21.jar file or nothing will happen.

I hope this helps, drop me a line if you have any more hassles. Good luck!

The error I receive is unexpected token: void. That error falls upon the void draw line.
