The other code, run on the computer which communicates to the external Arduino board via usb, is scripted in a language called Processing. The language is based on Java and remains quite similar to it, aside from some nice simplifications and many built in functions for working with graphics. The basic structure of the language is the same. You can see more information about it on the Processing site as well as download it for free. Arduino is actually a sister project of Processing and the Arduino language, although built on C is modeled after Processing.

Hi there, I know this sounds stupid, but is that code (not the arduino code – the processing and slider class) written in Java? It looks the same? If not please inform me. BTW, i like your idea very much! Great work!

The problem is on line 38 of the slider class.
I have a little problem with my CMS which will be fixed very soon. The ampersands in my code turn into funny strings. If you just fix that in the conditional statement on line 38 it should work fine. It should look like this

if ((mouseY<=ypos+thesize+10) && (mouseY>=ypos-10)) {

I tried everything, but I always get the same error:

“A web color (such as #ffcc00) must be six digits.”

Below that:

“Bad error line: -2″

I really don’t know how to move on, what am I doing wrong? I just need to send these values quickly, as I just want to regulate 2 motors because I have no Potentiometers left…
Any help would be appretiated.
