Hi everybody, I know this subject probably has a slew of related posts but.. i cant seem to find the answer to my specific problem. So im trying to make an object that takes flex sensor data and turns it into a google spread sheet and I accordingly tried out the awesome make magazine article detailing the process, however, although having followed the instructions diligently i end up getting the following error in my processing sketch " Cannot convert String to float" It specifically highlights the end of the code that read " float val = 0.0; "
ive posted a link to the entire code below

I just hope someone else figured it out and if so what do i do!!! if not can anyone give me another alternative perhaps. Unfortunatly i am a bit of newbie to the software ! any help would be awesome

It specifically highlights the end of the code that read " float val = 0.0; "

No, the line reads: float val = "0.0";

Sometimes, error messsages can be a bit cryptic, but I think this time, it is a model of clarity.

My apologies AWOL , it is in fact "float val = "0.0"; how very observant of you, however, beyond highlighting my incompetence any other advice to solve the problem would be rather welcome.

Seriously though, I'm kinda desperate here.

Well, taking the quotes off it would be a start, but I don't use Processing very much, so I'm not sure (though I can guess wildly) what happens when you do:val = port.read();
