I'm trying to get data from local port 80 into my processing sketch but it is not working.

When i put on my browser my host ip and local port (something like 169.254.186.203:80) i can see what was sent to the local port. So I tryed do get that into processing using the following simple WebClient sketch, but it doen't work.

Somebody can help me with this??

Thanks in advance

I need to use data from the arduino serial port in two classes (in the main class and in another one) ...

I already tryed to use serialEvent in both classes but it creates a conflict in the port....

How is the best way to do this?

Somebody can help me please??

Thanks in advance

I´m just trying to get a life time plot from temperature values, for that I built a sketch on processing based. To simulate the temperature values I used the position of the mouse.

The problem is that I just get a point running on time, not a line like I want. I think the mistake is on drawDataLine() function (last function).

Somebody can help me with this??

Thanks in advance
