Hi guys, so I was seeking some advice. I am presently working on an interactive handle that uses flexi force sensors to measure the amount of pressure a user puts throughout the process of getting up, using the aforementioned handle for assistance. Accordingly leds alert the user weather or not they've put a sufficient amount of effort into the action or not. However, although I've sorted out the mechanical portion of the piece I was wondering how best graph the data visually? Especially on a website. I need to create some sort of graph tht updates live on a website. I was considering flash or processing but I don't know if any of the above will render dynamically? Does anyone have any suggestions that would be quick and easy to integrate? Thanks!

Seriously though, I'm kinda desperate here.

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.

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
